What Is a Polyatomic Ion in Chemistry?

What Is a Polyatomic Ion in Chemistry?For a long time now there has been quite a bit of confusion about what is a polyatomic ion and the difference between an ion and a molecule. In fact it was very difficult to understand what is a molecule and what is an ion when I first got my chemistry degree. In this article I hope to clear some of that up and hopefully help you with your understanding.The Polyatomic Ion is basically a single particle. This is known as a molecular particle and it is what is referred to when a molecule is mentioned. The good news is that there are very many different types of polyatomic ions, some of which are very common in everyday life and some which are more rare.A second type of ion is the cationic or charging ion. There are a number of different types of ions such as the Azotheroide and the Monovalent. The most common are the Cationic and the Azotheroide, but there are other types of ions such as the Sialic, the Benzoic and the Nitrile.A Polyatomic Ion also has a valency and this is another term used in chemistry. A valency is simply a point on the ion when it is in an ionic state. This can either be positively or negatively charged and it may form a covalent bond with another molecule.Some of the things which may be confused between the Polyatomic Ion and the Hydrogen atom include the Hydrogen-air molecule. The Hydrogen atom is actually a molecule, but it cannot be easily distinguished from an ion in this manner. This is because the Hydrogen atom is surrounded by water, but it is not bound by water.The next time you find yourself confused about the difference between an ion and a molecule, it is best to ask someone who is an expert in the field. They may be able to help you understand the difference. Remember that they are experts and their experience will help you understand the whole picture.

The Rise Of Behavioural Economics In The 21st Century

The Rise Of Behavioural Economics In The 21st Century What Is Behavioural Economics? ChaptersBehavioural FinanceKey Figures in Behavioural EconomicsFind Out More By Reading Popular Behavioural Economics BooksBehavioural economics is a relatively new field within economics, compared to more established areas, such as neoclassical economics or post-Keynesian economic theory.Essentially, behavioural economics stands in opposition to classical economics. This is because behavioural economics, through a combination of both psychology and economics, is based on the assumption that people, when presented with economic decisions, do not always go with the rational option.Behavioural economists would argue that this is because individuals are not completely detached from their emotions when making economic decisions, and as such the heart can overrule the head at times.Classical and neoclassical economic schools of thought, on the other hand, believe that individuals:Are rational economic agents;Who are able to weigh up the benefits and drawbacks of a decision with objectivit y; andAre able to adjust and account for new information when making decisions.Until recently, neoclassical economics has enjoyed a period of almost unrivalled popularity, with many of the school’s theories and models taking pride of place among economics students and economists alike.However, with the rise of global events, such as the 2008 financial crisis, that could not be explained by traditional neoclassic economic models, other schools of economic thought are gaining even more traction. Behavioural economics, as a result, is enjoying a period of increased attention, and it’s easy to see why.With a number of Nobel prize-winning economists in the field, along with the fact that behavioural economics helps to better explain why we make the decisions we do, this relatively new, and growing field, will only gain traction.This article outlines some of the key areas of behavioural economics theory, while also highlighting some of the key figures within the field and their respec tive works.Behavioural finance examines trends in the stock markets. (Source: CC BY-ND 2.0, QuoteInspector, Flickr)Drastic plunges in stock market prices.There are many benefits to studying and understanding behavioural finance. For example, fund managers have a vested interest in understanding how behavioural finance may affect the investment decisions that they make, by helping such managers to understand the unconscious biases that they may hold which influence a decision to buy or sell an investment.Some of the main concepts of behavioural finance are outlined below.Confirmation BiasConfirmation bias is one way through which individuals have a tendency to interpret information in a biased manner. This happens because individuals tend to acknowledge evidence that supports their own interpretations or beliefs while ignoring evidence that may contradict them.Herd InstinctThe idea behind the herd instinct is people’s tendency to follow the actions of others without giving much con sideration as to whether they should actually be doing it.Herd instinct can be used to explain changes in the stock market, notoriously bubbles, for example, the dotcom bubble in the 1990s, and large-scale stock sales.Loss AversionLoss aversion is one of the cornerstone concepts of both behavioural finance and behavioural economics more generally. The theory posits that individuals feel the loss of something much more keenly than they feel about the prospect of gaining something. This means that individuals are happier to take a risk to prevent losses.Self-Attribution BiasAlso known as the self-serving bias, this concept has been studied in great detail within psychology. It describes individuals’ tendencies to attribute positive outcomes to their own abilities and knowledge, but to assign negative outcomes with events that were out of their control.Behavioural economics tries to make sense of stock market bubbles and crashes. (Source: CC0 1.0, Chrom72, Pixabay)Key Figures in Beha vioural EconomicsOver the years, a number of economists, and psychologists have emerged as prominent figures within the field of behavioural economics. Below are just a few of those pioneering economists, although you will come across many more if you end up studying behavioural economics in further detail.Daniel Kahneman and Amos TverskyKahneman and Tversky are, in some circles, considered to be some of the founding figures of the field of behavioural economics.Although Daniel Kahneman has done much to contribute to the field of behavioural economics, oddly enough, he is not actually an economist himself. A psychologist by profession, Kahneman worked with his late friend Tversky on a number of projects, with their collaboration spanning decades.In 2002, Kahneman received the Nobel Prize in economics for his contributions, although Tversky could not be in receipt of the award as well, as the awarding body does not grant posthumous Nobel Prizes.Some of their main contributions to the field of behavioural economics have been concepts such as:Loss aversion (as outlined above); andProspect theory, which in brief, posits that net losses and gains are valued and assessed by individuals differently.Richard ThalerRichard Thaler has certainly received a lot of media attention over the past few years and deservedly so. With a Nobel Prize in Economics under his belt, which was awarded in 2017, the general public’s interest in behavioural economics has continued grown along with the rise of Thaler’s ideas.Although Thaler has worked with Kahneman and Tversky previously, he is also known for his own achievements. He is perhaps most well-known for theories such as:Bounded rationality;Individuals’ inherent lack of self-control; andNudge theory.Of course, as with any area of economic thought, there are those that support the concepts outlined in behavioural economics, just as there are those that critique the field’s ideas.The main detractors of behavioural economics a re economists who believe in the concept of an efficient market, which is understandable, as essentially those that believe in efficient markets believe almost the opposite of what a behavioural economist would when it comes to analysing and predicting consumer behaviour!For instance, Eugene Fama, known as the founder of the theory of market efficiency, is not a fan of behavioural finance. One of his main arguments against behavioural finance is the fact that, while the efficient market hypothesis isn’t perfect, it’s better at predicting economic trends and behaviour compared to what behavioural finance or economics is capable of.There are lots of behavioural economics books you can read if you'd like to learn more about this area of economics. (Source: CC BY-SA 2.0, Ginny, Wikimedia Commons)Find Out More By Reading Popular Behavioural Economics BooksIf you find behavioural economics might be an area you’d like to study further, then it may be worth spending time reading some of the most popular books out there on behavioural economics.Not only should these works highlight some of the key concepts in behavioural economics, but they should also help familiarise you with the leading minds in this field, and the kinds of topics that you may end up studying if you took a behavioural economics module at university.Some popular, relatively accessible works include the following:Nudge: Improving Decisions About Health, Wealth, and Happiness, by Richard ThalerWhy Smart People Make Big Money Mistakes,  by Gary Belsky and Thomas GilovichThe Invisible Gorilla: How Our Intuitions Deceive Us, by Christopher Chabris and Daniel Simons; andThinking,  Fast and Slow, by Daniel KahnemanHowever, this list isn't exhaustive, so if you find a book on behavioural economics that appeals to you, or a friend or teacher recommends, then feel free to pick that up and give it a read instead. Ultimately, try to find behavioural economics books about topics that appeal to you, are writ ing in an interesting or engaging manner, and can help teach you something new about the field.If you’d like to learn more about behavioural economics and its key concepts, then you can also reach out to a tutor for some additional help and guidance. Superprof, for example, has tutors across a range of subjects, including psychology and economics.Simply let your economics tutor know in advance what areas of behavioural economics or behavioural finance you’d like to learn about, as this should then give your tutor plenty of time to prepare tailored teaching materials to help you get the most out of your tuition sessions. Superprof offers tuition in an online or in-person setting, on a schedule that works for you, so it’s never been easier to find a tutor to work around your schedule and budget.If you enter your postcode, then you can be matched with suitable local tutors in your area.

4 Tips for Connecting with Your Online Instructor

4 Tips for Connecting with Your Online Instructor The Internet has made possible a plethora of activities that could once only be done in person. Online learning is one such area. Online learning is an appealing alternative to the traditional classroom setting for a variety of reasons. The relative affordability, flexible scheduling, and overall convenience of online courses attract thousands of new students each year. But while online courses are gaining more recognition than ever before, students may have reservations about the seemingly impersonal nature of e-learning. However, connecting with your online instructor is a goal that students can reach by participating in live lectures, posting on discussion boards, and reaching out to the instruction through email. 1. Connect with your online instructor by actively contributing to discussion threads Most online courses have a forum component that counts toward a students participation grade. The instructor may pose questions for students to respond to, or students may be expected to formulate their own questions or topics for discussion. In either case, actively participate in the forum by both creating original posts and reacting to the posts of others. Directly ask your instructor questions that show you are completing all the assignments and thinking critically about the big picture of the course. Most instructors love to see dynamic dialogues in the forum and will respond to comments that are directed at them. [RELATED: How Online Learning Helps Students] 2. Connect with your online instructor by participating during live lectures Frequently participating in the live virtual classroom also makes a positive impression on your instructor. Participation can include using the raise hand feature, speaking or activating video when the instructor gives permission, and writing in the chat box or on the virtual whiteboard. Writing relevant, thought-provoking comments in the chat box during lecture is likely to get your instructors attention. However, avoid writing comments that are silly, offensive, or off-topic. Instructors tend to remember and connect best with students who are vocal with their ideas and encourage other students to become involved. Participation shows that you are an eager, conscientious student, which translates well to your rapport with the instructor. [RELATED: 5 Benefits of Using Videos to Learn] 3. Connect with your online instructor by periodically sending the instructor an email If you are the type of student who enjoys a more personal level of interaction, you can write your instructor an occasional email. Start with sending an email at the beginning of the course to introduce yourself and to say how interested you are in the class. Following your initial email, you can send a brief message every few weeks to ask how you are doing in the class and to see if your instructor has personalized advice for you. Instructors are often impressed by students who seek out self-improvement. As always, though, mind your email etiquette: Do not type in capital letters, as they can read harshly to the recipient. Always greet and end with a proper farewell, and use words like please and thank you when appropriate. [RELATED: 4 Ways an Online Tutor Can Help You Succeed This School Year] 4. Connect with your online instructor by keeping in touch To stay connected with your online instructor in the long term, keep in touch even after the course ends. Your instructor can be an excellent source for recommending other classes, methods for obtaining an internship or a job, or general academic advice. Online learning is different in many ways from in-person classes. Luckily, there are a variety of ways to develop a relationship with your instructor. Building that connection is in your hands.

Extended Test Time for Kids with ADHD

Extended Test Time for Kids with ADHD When kids and teens with ADHD qualify for accommodations at school, either through and IEP or 504 Plan, extended time on exams is often one of the academic accommodations provided. On the surface, providing students with ADHD with extended time on exams can seem like a great idea. After all, these students often take longer to complete assignments than students without ADHD, and on exams, they may only complete half the questions when their classmates without ADHD complete the entire test. So, extended time on exams seems like a reasonable accommodation that would give them the time they need to demonstrate their knowledge without being penalized for their ADHD symptoms. A closer look at the effects of extended time on academic performance, however, paints a picture that is much less straightforward. Lets start by talking about what extended time actually entails. Extended time typically translates into time-and-a-half (for example, 1 hours for a 1-hour test) or twice the allotted exam time. In addition to having more time to take the test, kids receiving this accommodation also take the exam in a separate room, either alone or with other students who have the same accommodation. Now lets take a look at some of the pros and cons of extended time: Being pulled out of class for exams. Taking exams in a separate room can be both a positive and a negative for students with ADHD. On the positive side, if they are in a room alone or with only a few other students, they may have an easier time staying focused. They may also have less anxiety if they are bothered by seeing other students finish first. On the negative side, students (particularly older elementary students and teens) who are sensitive to the stigma that can come with being singled out from your peers may resist the extended time accommodation altogether or feel uncomfortable with the situation. Addressing the underlying issue. There are many reasons why students with ADHD dont finish exams on time. Sometimes they have poor test-taking or reading comprehension skills; other times, they struggle to stay focused and work productively on a relatively boring task for even 10 minutes (and extending the length of the task doesnt improve their productivity); in other cases, anxiety is the culprit, and extended time doesnt reduce anxiety effectively. In some cases, slow processing speed is the underlying issue, which may actually be addressed by extended time. For students who have deficits in areas related to test-taking skills or who have test anxiety, addressing the underlying issues will be more effective than an extended time accommodation. Does it really improve academic performance? While only a handful of studies have looked at the effects of extended time on test grades and academic performance in students with ADHD, the findings generally show that there is no academic benefit.1 One exception is a study that looked at test performance in students with ADHD who had poor reading comprehension skills. Those students did seem to benefit from extended time. The one caveat here is that these studies were largely done in controlled environments and not in a typical noisy classroom setting. So, the real-world academic benefits for an individual student may be different from what this limited research has shown. Overall, extended time on exams is an accommodation to carefully consider for your child or teen with ADHD. It may be beneficial for some students and not beneficial for others. If you decide to include extended time as part of your childs 504 or IEP plan, monitor their progress. Are they showing academic improvement? Do they say that its helpful to take their exams in a separate room? Or do they find the pull-outs disruptive or stressful? When extended time is provided, its important to make sure that the underlying test-taking challenges are also addressed, whether thats treating the test anxiety, teaching strategies for improving the rate of information processing, or coming up with creative ways to improve concentration during exams (e.g. wearing noise-cancelling headphones while taking exams in the classroom). As is often the case with ADHD, there is rarely a one-size-fits-all solution, and its up to parents and teachers to find creative and comprehensive ways to help students r each their full potential. 1Brown, T.E., Reichel, P.C., Quinlan, D.M.

Whats a Good ACT Score

What’s a Good ACT Score ACT SAT Prep and College Admissions Blog Recently, a parent contacted MyGuru about ACT tutoring. Her daughter’s first session with the tutor went well, but because she was scheduled to take a practice ACT test in school the next week, they waited to schedule another session until the results of that test were available. Unfortunately, her daughter did worse than expected on this practice ACT test, and so the parent contacted MyGuru to confirm a desire to invest in ACT tutoring and schedule additional sessions. In the course of the discussion, this parent asked a targeted question to which I didn’t have an exact answer on the spot. I figured that I should find the answer to this seemingly basic question, as other parents or students will probably ask it. The question was, “what is the minimum ACT score required for admission to common Illinois universities, like the University of Illinois, Illinois State University, Northern Illinois, etc.”? There’s a reason I didn’t know the answer to this question off the top of my head â€" it’s a bit of a trick question. A little basic research reminded me that most colleges and universities really don’t have minimum ACT scores. Instead, they report the average ACT score for the middle 50% range of admitted students. Here’s what this means. First, line up all of the admitted students at a given school and rank them according to ACT score. Then, remove the top 25% of students, as well as the bottom 25% of students. What you have left is the middle 50% of students â€" essentially, you have a bottom and top end ACT score for the “average” admitted student. For example, at the University of Illinois, the middle 50% ACT range is 27 to 32 for admitted students. Then, in terms of what this means for admission, what most colleges do these days is say something like â€" Here at College XYZ, we have a holistic application review process. GPA, ACT/SAT, activities, coursework, etc. all play a part in the process. So, we don’t have a minimum requirement. But, here’s the ACT range for the middle 50% of admitted students. If you fall below the middle 50% range, you should make sure the rest of your application demonstrates your ability to succeed here. For example, at Illinois State University, the ACT range is 22 â€" 26, and the GPA range is 3.1 to 3.8. On their admissions web-site, they write “The chart below shows the middle 50 percent of students who were offered admission to the University for fall 2012. It may be in your best interest to submit an academic personal statement if you fall below or in the lower end of one or both of the ranges listed.” In other words, if you aren’t in those ranges, you need to explain yourself a bit via the optional “academic personal statement.” The Sliding Scale of GPA vs. ACT score In my opinion, informed by personal experience and conversations with admissions counselors, some of the larger, more selective universities have a “sliding scale” of GPA vs. ACT score. In other words, assuming you took high school classes with a reasonable level of difficulty, if your ACT score is relatively low, you can make up for this by having a relatively high GPA, and vice versa. But, if you fall outside of the “acceptable” range according to this sliding scale, you probably won’t get in. However, at smaller schools, they really do take a more holistic look at you as an applicant. For example, someone with great extracurricular activities and a really high ACT score might have a much better chance of getting into a prestigious smaller liberal arts school than their large state university, even though the liberal arts school is actually “ranked” more highly and is considered more selective. So, here’s how you can evaluate your ACT score or determine your required ACT score: Identify a list of schools you might want to attend Find the middle 50% range at potential schools See if your ACT score is within or above that range Here are some example ACT score ranges for popular Illinois colleges: To keep things simple, let’s take a quick look at three Illinois universities: University of Illinois â€" Urbana:A very selective school that’s consistently ranked in the top 50 by U.S. News and World report Middle ACT Range â€" 27 to 32 Illinois State University: A less selective state school, but one that only accepts motivated, intelligent students capable of pursuing a rigorous college education Middle ACT Range â€" 22 - 26 Southern Illinois University: A state school with a similar mission to Illinois State, but one which is even less selective Middle ACT Range â€" 18-24 What if your ACT score isn’t very good? How low can you go? Well, that depends. ACT, Inc. hopes students and colleges use the ACT to determine college readiness. They write that â€" “Only the ACT reports College Readiness Benchmark Scores â€" A benchmark score is the minimum score needed on an ACT subject-area test to indicate a 50% chance of obtaining a B or higher or about a 75% chance of obtaining a C or higher in the corresponding credit-bearing college courses, which include English Composition, Algebra, Social Science and Biology. These scores were empirically derived based on the actual performance of students in college.” The College Readiness Benchmark Scores are: English: 18 Math: 22 Reading: 21 Science: 24 Average: ~21 So, if your composite score is below 21, or any of your sub-scores are below the above numbers, you can probably expect all but the least selective colleges to think twice before admitting you. Of course, a strong GPA can certainly make up for weak ACT scores.
