 * 1. what is a covelant bond?**
 * A chemical bond that shares a pair of electrons between atoms in a moecule (book)[]

**2. what is an ionic bond?**
 * An ionic bond (or electrovalent bond) is a type of chemical bond based on electrostatic forces between two oppositely-charged ions. Source: [|**http://sciencehack.com/videos/view/xTx_DWboEVs**]

**3. List 5 differences between ionic and covalent compounds (Ex. high or low boiling and melting points, sharing or transferring electrons, etc.)** 1. Ionic bonds are formed between the attraction of cations and anions. 2. Covalent compounds exist only as molecules. 3. ionic compounds are crystals of ions. 4. In covelent compounds the atoms share electrons 5. Ionic compounds transfer atoms between metals and nonmetals.


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

 * __Nitrous acid- HNO2__**

I used my notes and saw that Nitrous ended in -ous so i knew it ended in ite. This makes Nitrous Nitrite (NO2). It takes one Hydrogen to balance Nitrite.


 * __HF- hydroflouric acid__**

I used my notes to turn flouride into hydroflouric because the ending -ide will turn the ending into -ic and ats the prefix hydro. when naming an acid you always but acid after the first name


 * __C4H8- tetracarbon octahydride__**

you add the prefix tetra to carbon because there are four and octa to hydrogen because they are both nonmetals making it a covalent bond.


 * __Iron(III) Sulfate- Fe2(SO4)3__**

I looked at sulfate (SO4) and it had a charge of 2-. to balance it out i gave iron(III) 2 and (SO4) 3. its a ionic bond.
