Organize these into the right naming type when they come first

Name as usual

Needs a Roman Numeral between names

Needs Prefix to tell number of atoms

Polyatomic Ions have a set formula

and are not allowed to change

If you change the atoms of the

polyatomic it becomes something

new and that is not allowed

Calcium Phosphate

Cross and Drop! Reduce if You Can

Step 1: Calcium

Step 2: Ca²⁺ PO4^-3

Step 3: Ca

Find the oxidation State of the

polyvalent metal with a polyatomic

ion

Remember the charge of polyatomic is on the back of your P.T.

Subscript Metal (X) + Subscript polyatomic ion( Ox #) = 0

State metal, use Roman Numeral for oxidation state, state polyatomic

name

Type Five: Polyvalent metal and a Polyatomic Ion
