Tertiary Compounds
Polyatomic Ions:
1. Write the formula for the following tertiary ionic compounds using the following rules:
1.
2.
3.
4.
Identify and write in the charges of the cation and polyatomic ion in the compound
Put parentheses around the polyatomic ion
Criss-cross the charges
Reduce subscripts OUTSIDE the parentheses if necessary (do not reduce the subscripts of the
polyatomic ion inside the parentheses – it must stay as is!!)
a. lithium sulfate
b. calcium nitrate
c. copper(II) permanganate
d. strontium hydroxide
e. chromium (III) carbonate
f. manganese (IV) sulfite
g. barium chlorate
**h. ammonium sulfate
2. Name the ionic compound using the following rules:
1. Name the cation
2. Name the polyatomic ion
a. NaNO3
b. Ca(CN)2
c. Mg3(PO4)2
d. Al(OH)3
e. ZnSO4
f. Cs2CO3

3. Name the ionic compounds that are made from transition metals using the following rules:
1. Write in the charge for the anion you are sure of
2. Work backwards to find the charge of the cation
3. Name the cation and anion
4. Include the roman numeral in the name
a. CuS
b. FeP
