1. What is a covalent bond?
 * A covalent bond is a bond between a two or more nonmetals.

2. What is an ionic compound?
 * An ionic bond is a bond between a metal and a nonmetal.

3. List 5 differences between ionic and covalent bonds. __Ionic Bonds__ Transfer electrons Metal & nonmetal High melting points Crystalline solid at RTP Crystals

__Covalent Bonds__ Share valence electrons Two nonmetals Low melting points Gas or liquid at RTP Molecules

4. Find 5 Lewis Structures and copy and paste them on your page. Determine their molecular geometry. Bent Linear  Bent Trigonal Planar Octahedral

3/22/10 - **__Guide to Naming and Writing Formulas for Chemical Compounds__**

tetranitrogen heptoxide (given) - N4O7 -As a covalent compound, I know that its going to include prefixes. Tetra- means four, so there's 4 nitrogens, and hepta- means 7, therefore there's 7 oxygens.

{Pictures of this are unobtainable. :P}

ammonuim nitrate (given) - NH4(NO3) - This is ionic as far as I know. Since I got that one sheet with a bunch of polyatomics on it, I've used it on a lot of things. This is one of them. :)



HCl (given) - Hydrochloric acid -This was an example in the notes, and it was on Mr. Walk's page, but I used Rule #1 on my notes since its obviously an acid. They whole thing with the charges and then the prefix hyrdo- and the suffix -ic was done and all that fun stuff.



Carbonic acid (given) - H2CO3 -This was on the notes too, but I used Rule #3 since, once again, its an acid.. The suffix -ate with carbonate gave me CO3, then -ic had to go on. Oh, and let's not forget the word acid.



Here's where the pictures are from: Yeah, I can't find a picture of this one... [] I got the HCl picture from Mr. Walk's page. :D []
