If you just guess metal, you'll be right more than half the time.

mono = 1\ndi = 2\ntri = 3\ntetra = 4\npent = 5\nhex = 6\nhept = 7\noct = 8\nnon = 9\n\nnonmetals:\nif there is no prefix for the first element, it is assumes to be one.\nTHe ening of the anion (the second one listed) is changed to -ide.\n\ncarbon - 1 \noxygen - 2\nCO2  <---The number is a subscript, but you cant do that on here\n\nPhosphorous - 1\nIodine - 3\nPI3\n\nHydrogen - 2\nOxygen - 1  (it should be monoxide)\nH2O\n\nHope that helps you.  Don't feel bad; you can't know what you haven't learned.

choose the noble gas that comes before the element.   in Mn(2+)'s case, that's Ar\n\nwrite the noble gas down in brackets, and continue on with the electron config. as normal\n\n[Ar}4s23d3\n\nFor O(2-), it turns into Neon so it would just be [Ne]

d)Argon: 1s2 2s2 2p6 3s2 3p6\ne)Could be carbon, silicon, germanium, tin, or lead.  It's not specific enough.  And there is no such thing as an "elemen." Please treat chemistry with enough respect just type a "t" at the end of a word.  \nCarbon: 1s2 2s2 2p2\nSilicon: 1s2 2s2 2p6 3s2 3p2\nGermanium:  1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p2\nTin: 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4d6 5s2 4d10 5p2 \nLead: \n1s2 2s2 2p6 3s2 3p6 4s2 3d10 4d6 5s2 4d10 5p6 6s2 4f14 5d10 6p2

Just think of some words and see if you can spell them from the symbols of the elements.  \n\nchocolate = C H O Co La Te

Write it down and look at it every once in a while. The other thing I do to remember numbers is to associate it with something that I cannot forget. Analogies work greatly in memory!

I remember this question since it was on the test once:\n\nList the following kinds of matter by how well they conduct heat (from the best to the worst): Wood; air; metal; water.\n\nMy answer was the correct one and it was: Metal; water; wood; air.

Here's a great website with pictures of the various nobel gases in lamps so you can see their glows and describe them yourself.\n\nhttp://www.assumption.edu/users/bniece/Spectra/Complete.html

The tip I give to my student is to always FINISH with the element that has only one type of atom, like O2 or H2.  This way, when you balance it, you won't disturb any work done previously.

Helium, CO2, Hydrogen and various others.

To remember any fact, and especially one in a foreign language, you need to attach a PICTURE in your mind to the fact and words.\n\nFor example, suppose you want to remember that "Ahorn" means "maple" in German. A-horn of plenty full of maple syrup on the Thanksgiving table of the Pilgrims. Picture it! \n\nOr suppose you want to remember that Hydrogen is Wasserstoff in German. Remember that WATER (wasser) is STUFFED full of hydrogen (h2o) \n\nSuppose you want to remember that "Gift" in German means "POISON" and not "a present" --you imagine the wicked stepmother giving you a GIFT of a poisoned apple. \n\nSomething like that. Use your mind to make pictures.

Improving your memorising really depends on what kind of learner you are..\n - If you are visual you need to associate things with images or set them out in a way that is easy for you to understand. You can work on your visual memory by drawing diagrams, staring at them for a while, then re-drawing the diagram on a blank page until you remember the whole thing. This helped me with a lot of biochemistry exam questions!\n - If you're an audio learner, you need to hear what you're trying to learn. You can do this by recording your voice reciting what you need to learn or by telling someone else what you need to remember (even if it's an inanimate object or a pet, it actually works).\n - If you learn by actually doing things, then the best way is to write out what you need to learn and keep on writing until you remember.\n\nAs for help with getting extra marks in exams, the best method is to start with the questions you know you can answer easily first. Then if you hit a question that is taking you too long, leave it and then come back to it later. And if there's something you don't remember as a part of a question, at least attempt to answer what you can because you can grab extra marks without answering the whole question.\n\nGood luck! :)

I memorized by going over and over the material, just spending alot of time looking at it.  Also, exactly like someone else said, I have made flash cards from index cards, write the term on one side and the answer on the other.  I would punch a hole in the upper corner and put them on one of those rings that open and clasp shut.

a) Ag2S\nb) SnCl4\nc) Na3N\nd) SrI2\n\nDo us a favor and pay attention during class. That way you'd know how to do these.

You have to memorize this table there is no way around it. Remember it and you should do great. http://www.brynmawr.edu/Acads/Chem/mnerzsto/SN2vsE2_flowchart.htm
