1.What is a covalent bond? A chemical bond between atoms in which they share electrons. (1)

2.What is an ionic bond? A bond formed when electrons transfer atoms. (2)

3.List 5 differences between ionic and covalent compounds (Ex. high or low boiling and melting points, sharing or transferring electrons, etc.).

**__Ionic:__** Bonded by electrons with opposite charges (3) Usually nonmetals and nonmetals (4) Ions can separate when in water (5) Usually solid at room temperature (5) Unstable compounds (5)


 * __

Covalent: __** Bound by shared electrons (3) Usually metals and nonmetals (4) Cannot separate in water (5) Usually liquid at room temperature (5) Stable compounds (5)

4.Find 5 Lewis Structures and copy and paste them on your page. Determine their molecular geometry.

Oh yeah. I thought that it was weird to put my name in the title, so I'll put it in here I guess?

Zinc (III) Phosphate: Zn3 (PO4)2

I determined that the formula is Ionic because Zinc is a transition metal, so I knew to use the ionic way to find the formula. Then I found the charges of Zinc and Phosphate. Finally, I made their charges fit by multiplying them.

N3O7: Trinitrogen heptoxide

I realized that the formula is carbonic because Nitrogen is a gas, so I used the Since Nitrogen has a charge of three, I looked at the prefix for three and put it before nitrogen. Then I found the prefix for seven, changed oxygen to oxide, and put the suffix and word together. It's magical.

H3P: Phosphoric acid

Hydro says that it's an acid, so I looked under the acids for a formula that matched. It was Hydrogen phosphIDE, so I used to first option and changed phosphide to phosphic. Then I added acid.

Sulfuric acid: H2(SO4)

The formula is an acid because it's labelled as an acid in the given information. So I reversed to process, first by figuring out what sulfur was originally ( sulfate). Since it had -ate, it was rule #3. Also, the acid part made it have hydrogen at the beginning of the formula. Then I put Hydrogen and Sulfate together, making them fir by multiplying their charges to make them the same.

I can't figure out how to do those stupid letters right. So just use your imaginiation.
