Compounds and such

• Ionic compounds do care about charge
• Typically consists of metal cations and non-metal anions
• Charge in an ionic compound must be neutral
• Naming ionic compounds: Two components; Cation name for first element. First part of name + -ide for second element (because it is negative)
• Polyatomic ions: Majority are anions... E.g. hydroxide=OH-
• Transition metals need a roman numeral
• Polyatomic ends in -ate
