How to Define Ionic Compound in Chemistry

How to Define Ionic Compound in ChemistryIn order to learn how to define ionic compound in chemistry, you need to understand that ionization is the movement of an electron from one atom to another. This can happen by bonding or by un-bonding.An example of an ionic compound is a metallic element with a definite number of electrons: negative ions. The positively charged atoms are bonded together with a type of covalent bond. When the bond is broken, the electrons move into the atom. The moving electrons produce electrical charge and this is what is known as an electric field.There are several ways to break bonds in the metal; and these usually have a negative effect on the metallic atoms. For example, when oxygen atoms bond with the carbon atoms of certain metals, the metal is referred to as a non-metallic element. Such elements are referred to as metallic.When you learn how to define ionic compound in chemistry, you will find out that an ionized compound is a chemical formula that has two electronegative ions. You will also learn that most chemical reactions need to be done in a closed system. This means that only molecules with no or few voids exist within the system.An example of an ionic compound is water that has a reduced concentration of oxygen and a charged electrostatic field. Water has the ability to attract and repel water molecules with a specific electrostatic charge. With a charged water molecule, a positively charged electron is free to move to another atom.It is easy to see that how to define ionic compound in chemistry begins by knowing something about how the chemistry works. With such knowledge, you can begin to think about certain combinations of compounds that would allow you to understand what is going on inside a system. For example, you may know that the crystal structure of a complex molecule is determined by the arrangement of atoms.In addition, you may know that it is the electrons that are used to hold atoms together that cause a certa in chemical reaction to occur. The complex molecule would not function if the electrons were not bound. Therefore, it is easy to say that a substance has two electronegative ions if it has electrons that are linked in a manner that binds the electrons to make a two-electron bond. In some cases, one or more electronegative ions are present.Understanding how to define ionic compound in chemistry is not that difficult. With knowledge of chemical bonds, and the need for an ionic compound to have two or more electronegative ions, you can understand why it is necessary to look at each component separately. By learning the distinction between electronegative and ionic compounds, you can better understand how chemistry works.

How to Create a Last-Minute Study Plan for Finals

How to Create a Last-Minute Study Plan for Finals Finals season is upon us. Even though you may have already been tested on much of the material that will appear on your finals, you will need to develop a greater understanding of that material in order to earn a high score on the final. Developing a plan to approach your exams can not only help you stay organized as you study, but can also help you reduce some of the stress that comes with reviewing mass amounts of detailed information. But what can you do ifyour finals are less than a weekaway? Check out these tips on how to create a last-minute study plan for finals: 1. Develop a list of all of the topics on which you will be tested A good place to start studying for your finals is to develop an understanding of how much you will have to master and how much time you have to study. Begin by taking stock of each course in which you are enrolled. Which concepts will you have to review? Which concepts are the most in-depth, and which will you spend the least time on? Make a list of review topics for each of your subjects, prioritizing the more difficult and prominent topics. 2. Plan ahead by studying for each subject over several days, instead of cramming The worst position to be in is to stay up until the wee hours of the morning to cram the night before a final exam. Avoid this by using a planner or calendar to plan which topics youll tackle each day. For example, on one day you might study differential functions from calculus, another topic from chemistry, and two additional units from history. Studying all of your subjects over a longer period of time gives you plenty of time to revisit difficult topics and adjust your study habits if necessary. Plus, research indicates that your brain better retains information when it intakes new material over shorter periods of time, rather than an hours-long cram session. Also, many students may intend to study for, say, math and literature on one day, but end up focusing entirely on one subject, without moving on to the next. Planning ahead helps alleviate this problem. If you know a particular subject will take up a great amount of study time, plan for it. Take into account your needs and test dates to make sure you dont put off studying for any subject. 3. Take notes on concepts youll need to review closer to the test As you study, take notes on topics that you know will require some last-minute review before your final. Make sure these notes are organized and comprehensive, but are concise enough to review in the day or two before your exam. You can also tailor your review to your learning style by drawing illustrations, mind maps, or graphics if you are a visual learner, for example, or reading your notes aloud if you are an auditory learner. [RELATED: How to Identify Your Study Style] 4. Complete practice problems for each of your topics The best way to get ready for a finalespecially one that involves quantitative problemsis to answer questions and solve problems concerning the topics you will be tested on. For example, when preparing for a final in your College Algebra class, you should take the time to solve college algebra practice problems that correspond with each unit you are reviewing. Even in non-math courses, like American History, you may come across practice questions to supplement your review. Testing yourself before the real exam is the best way to put your knowledge to use and hone your critical thinking skills. [RELATED: How to Analyze Practice Test Results] 5. What to do the night before a final exam Ideally, youve been studying for weeks, but you could also use a last-minute refresher. What do you do? If you listened to our advice and took notes on difficult topics to review, you can use these notes as a last-minute review sheet to hone your understanding. Review your notes and then go to bed earlya rested mind and body help you perform the best you can on test day. It may seem like finals sneak up on you, but you can control the process with forethought, focus, and review. Start your study plan for finals today, and see the results by test day.

What is it Like to Attend Columbia University

What is it Like to Attend Columbia University The tutors behind Varsity Tutors are not just here to teach theyre sharing their college experiences as well. Julia is a New York City tutor and 2012 graduate of Columbia University. She majored in Ecology and Evolution Environmental Biology. Julia specializes inseveral subjects including Geometry tutoring, Statistics tutoring, and Organic Chemistry tutoring. Check out her review of Columbia: VT: Describe the campus setting and transportation options.How urban or safe is the campus?Are there buses or do you need a car/bike? Julia: Columbia is in New York City, of course, so public transportation is excellent. The 1 line on the subway will take you wherever you need to go in Manhattan, and theres a bus that stops at Columbia that goes directly to LaGuardia Airport. As for safety, New York City in general and the Columbia neighbourhood in particular are much safer than people think. Its not the 80s anymore. VT: How available are the professors, academic advisers, and teaching assistants? Julia: Professors and TAs are generally very personable and available, unless your professor is someone really famous, like Jeffrey Sachs. Academic advisers are available by appointment, but arent terribly helpful. If you have a problem with your schedule or your credits or anything else academic, you need to take the initiative. Try to solve it yourself, and if you cant, then go to your adviser with specific demands that they can fulfill. VT: How would you describe the dorm life rooms, dining options, location, socialization opportunities with other students? Julia: The rooms arent great until senior year, but honestly, who cares? Youre in New York City. People pay $1000/month to live in much worse housing than this, and if you dont like it, you can always strike out on your own and live off-campus. The housing for seniors is fantastic, though. The food is pretty bad at Columbia, but you can use your dining plan to eat at the Barnard cafeteria, which is better. All the same, Id advise that you get off the meal plan as soon as possible. I started cooking for myself my sophomore year, and the upshot is that Im a much better cook than most people my age. As for location and socialization that hardly needs saying. If you use your evenings well, youll make tons of friends both on and off campus. Im from New York and even so I can say I had my most thrilling urban adventures while at Columbia. VT: Which majors/programs are best represented and supported?What did you study and why? Did the university do a good job supporting your particular area of study? Julia: The biggest majors at Columbia are History, Economics, and Political Science, but youll find incredibly dedicated and intelligent people in every department. My major was Ecology, Evolution Environmental Biology, which I think is a hidden gem at Columbia. Everyone in the major does a thesis, which gets generous funding from the department. I had the opportunity to do my thesis research in Kenya. VT: How easy or difficult was it for you to meet people and make friends as a freshman? Does Greek life play a significant role in the campus social life? Julia: Making friends at Columbia is easy if you want to make friends. You cant be shy or passive about it. If you dont reach out to people, you could float along in a bubble of solitude and no one will notice. But if you go out, talk to strangers, take part in campus activity, then youll have more friends than you know what to do with. I know I did. There is absolutely no need to take part in Greek life to make friends in fact, Id advise against it, given all the recent scandal with Columbia fraternities. They constitute less than 10% of the undergraduate body and have a poor reputation to boot. VT: How helpful is the Career Centerand other student support services?Do many reputable companies recruit on campus? Julia: Not very helpful. If you want an administration that will nurture you and guide you every step of the way, dont go to Columbia. There are millions of opportunities available to Columbia students, but you have to find them yourself. No one will show you the way. Thats not to say that there arent recruiters on campus, but the most aggressive ones are from Wall Street banks, and frankly I think theyre evil. VT: How are the various study areas such aslibraries, student union, and dorm lounges? Are they over-crowded, easily available, spacious? Julia: The libraries are numerous and architecturally beautiful. Be sure to branch out beyond Butler, our most famous and most used library, especially around finals time when it gets crowded. Im personally fond of the Teachers College library, which is great for group study sessions because youre allowed to talk, within reasonable volume limits. VT: Describe the surrounding town. What kinds of outside establishments / things to do are there that make it fun, boring, or somewhere in between?To what extent do students go to the downtown area of the city versus staying near campus? Julia: I dont know what to say about New York City that people dont already know. Its constant excitement. If you want to do something completely new and mind-boggling every single day, you can (though youll exhaust yourself very quickly.) Columbia is in Morningside Heights, which compared to the rest of Manhattan is pretty low-key, though low-key for Manhattan is high-octane compared to anywhere else. One thing Ill say is that not enough Columbia students venture out of Morningside Heights. Theres plenty to do in the neighborhood, but to me it seems the pinnacle of laziness to forgo a short trip on the subway to enjoy the rest of the city. VT: How big or small is the student body? Were you generally pleased or displeased with the typical class sizes? Julia: Columbia is just about medium-sized in the scale of things: big enough that you can maintain your privacy, small enough that you dont get lost in a faceless crowd. The class sizes never bothered me. Obviously, something like Intro Chemistry is going to be a big lecture class, but all the core curriculum classes are small, as all the really important classes are. VT: Describe one memorable experience with a professor and/or class. Perhaps one you loved the most or one youregretthe most. Julia: Columbia is famous for its core curriculum, a suite of classes that everyone must take. Personally, I had a great time with the core curriculum and Ill never forget my Contemporary Civilization class. The professor was much like Socrates, the ancient philosopher about whom we read so much: he questioned everything the students argued. He let no belief go unfounded, no unconscious bias go unmasked. By the end of the class, I internalized him. I interrogate everything I hold dear, and anything that can survive that scrutiny I keep, and anything that doesnt hold up I discard. I think the core curriculum turns you into a very thoughtful person, if youre willing to open your mind and give up your pretensions. Check out Julias tutoring profile.
