4 areas of high density, one lone pair = TRIGONAL PYRAMIDAL
 * What is a covalent bond? A **covalent bond** is a form of chemical bonding that is characterized by the sharing of pairs of electrons between atoms, and other covalent bonds. Source: Wikipedia
 * What is an ionic bond? An **ionic bond** is a type of chemical bond that involves a metal and a nonmetal ion through electrostatic attraction. Source: Wikipedia
 * List 5 differences between ionic and covalent compounds (Ex. high or low boiling and melting points, sharing or transferring electrons, etc.). In an ionic bond there is complete transference of electrons while in covalent there is sharing of electrons. In an ionic bond, the atoms are bound by attraction of opposite ions, whereas, in a covalent bond, atoms are bound by sharing electrons. In covalent bonding, the molecular geometry around each atom is determined by VSEPR rules, whereas, in ionic materials, the geometry follows maximum packing rules. Ionic bonds are usually associated with inorganic compounds. Covalent bonds are usually associated with organic(carbon-based) compounds. Source: Answers.com

(Given) H2CO3 - (Name) Carbonic acid

(Formula) H3N - (Given) Hydronitric acid
 * Rule III says that an anion ending in -ate means that the acid name is the stem of the anion with the suffix -ic followed by the word "acid"
 * Rule I says that hydronitric acid must be a combination of hydrogen and nitrogen. Hydrogen has three to balence out the charges.

(Given) C2O6 - (Name) Dicarbon Hexaoxide
 * Since both elements are nonmetals and there was no carbon, I knew that I had to use prefixes.

(Formula) MN3(PO4)2 - (Given) Manganese (II) Phosphate
 * Due to the Romanian numeral, I knew that this compound had a transition metal with a charge of 2+. So, I put in the required amount of atoms to balence out the charges.
