Categorizing Compounds Group the ions and compounds in your list into 5 groups and describe each group.
Label each group using these terms. Anions Cations Monoatomic Polyatomic Binary Compounds Ternary Compounds
Definitions Anions – Cl, Br, I, F, S Cations – Na, Mg, Ca, Sr, Li
Definitions Monoatomic – all cations and anions Polyatomic - PO 3 -3, OH -, NH 4+, SO 3 2-, H 3 O +
Definitions Binary Compounds - Ba 3 N 2, Na 2 S, Zn 3 N 2, FeCl 2, Cu 2 S Ternary Compounds - K 2 SO 3, NaClO 4, NaMnO 4, H 2 SO 4, CaCO 3
