1. Nomenclature for Binary Compounds
I Ionic
II Ionic
III Covalent

2. Covalent Compounds
Covalent cmps have covalent bonds involving electron sharing
Covalent bonds form between two non metals.
Type III: name more cation-like first; use prefixes to identify number of each atom.

3. Ionic Compounds (IC)
IC have ionic bonds due to transfer of electrons and then attraction of oppositely charged ions.
IC are cmps containing a metal (+; name first) and a non metal (-, name second with –ide ending), or a polyatomic ion.
Type I: IC whose cation has a single common charge state. IC must be neutral.
Type II: IC whose cation has more than one common charge state. Use (RN) to identify charge state. IC must be neutral
