What is a covalent bond? What is an ionic bond? List 5 differences between ionic and covalent compounds (Ex. high or low boiling and melting points, sharing or transferring electrons, etc.). Find 5 Lewis Structures and copy and paste them on your page. Determine their molecular geometry.
 * [|//http://www.wisegeek.com/what-are-covalent-bonds.htm//]  states that Covalent bonds  are the strongest type of [|chemical] bond and are created between atoms with similar electronegativity.
 * [|//http://www.wisegeek.com/what-are-ionic-bonds.htm//] states that Ionic bonds are a type of electrostatic bond between two atoms that is weaker than covalent bonds, but usually stronger than [|hydrogen] bonds or the van der Waals force, which is what holds water to itself.
 * According to [|//**http://www.diffen.com/difference/Covalent_Bonds_vs_Ionic_Bonds**//]**,** 1. Covalent has a low boiling point while Ionic compound has a high boiling point. 2.Covalent Bonds occur with two non-metals but Ionic bonds occur one metal and one non-metal. 3.At room temperature, Covalent Bonds are liquid are gaseous. But in Ionic Bonds, They are solids at room temperature. 4.Covalent Bonds have a definite shape while Ionic Bond's molecule have no definite shape. **Also,** [|//http://chemistry.about.com/od/chemistrystudentfaqs/f/bondtypes.htm,**C:In**//] 5.stated that an Ionic Bond, the atoms bound together by the attraction between oppositely-charged ions. But in a Covalent Bond electrons shares equally between atoms **.**

1. H3PO4- Phosphoric Acid; This uses rule 2, which states that "when the anion name ends in -ate, the acid name is the stem of the anion with the suffix -ic, followed by the word acid." So in order to put this rule in affect, i needed an acid. (H3PO4) And this is an acid because it contains Hydrogen. Then I found that PO4 is a polyatomic ion with an -ate ending. To follow the rule, i changed -ate to -ic, and added the word acid to the ending of the name.

2.Lithium Hypochlorite- LiClO; This compound has a metal (Lithium) and is combinding to a polyatomic ion with the same charge to balance it out. so to write it, all you need to do is write their regular symbols. (only becasue their charges are balanced)

3.dichromic acid- H4(CrO4)2; This uses rule 2, which states that "when the anion name ends in -ate, the acid name is the stem of the anion with the suffix -ic, followed by the word acid." So in order to put this rule in affect, i needed an acid. (H4(CrO4)2) And this is an acid because it contains Hydrogen. Then I found that CrO4 is a polyatomic ion with an -ate ending. To follow the rule, i changed -ate to -ic, and added the word acid to the ending of the name.
