Indication of Type of Compounds:
ide- binary coumpound-2 elements only
ate/ite- polyatomic ion involved- most anions; only cation- ammonia
Naming Chemical Compounds:
Cation Main Groups
o (+1) group one metals w/out hydrogen
o (+2) group two metals
o (+3) group 3- only Al, Ga, and In
Anion Main Groups
o No noble gases
o (-1) F-I
o (-2) O-Te
o (-3) N and P only
Transition Metals
o The only two that only have an unchanging charge are Zinc (+2) and Silver (+1)
o All others have variating charges
Examples (all ionic):
a) BaCl2- barium chloride (only one charge involved)
b) CrCl3- chromium (III) chloride (use roman numerals when more than one charge
