4. Three types of ionic compounds
Type 1 - Binary compound (contains only two elements) and cation charge is known because atom can form only one type of ion.
Metal forms only one type of ion: Groups 1A, 2A, Al3+, Ga3+, Zn2+, Cd2+, and Ag+
Type 2 – Binary compound with variable charge cations.
Transition metals and representative metals.
Type 3 – Polyatomic ion compound contains three or more elements contained within one or two polyatomic ions.

5. Type 1 Ionic Compounds
Formed by electron transfer from a metal to a nonmetal
Metal forms only one type of ion: Groups 1A, 2A, Al3+, Ga3+, Zn2+, Cd2+, and Ag+
Name as metal nonmetalide
Name

6. Type 2 Ionic compounds – Transition Metals
Most transition metals and group metals form multiple ions.
Cr, Fe and Co form 2+ and 3+ ions
Cu forms 1+ and 2+ ions
Sn, Pb form 2+ and 4+ ions
Mercury (II) is Hg2+, while Mercury (I) is Hg22+
Named as metal (roman numeral for charge on metal) nonmetalide
Name
Formula
lead (II) oxide
CuO
