Polyatomic Ions
You can make additional polyatomic ions by
adding a H+ to the ion!
CO3 -2 is carbonate
HCO3– is hydrogen carbonate
H2PO4– is dihydrogen phosphate
HSO4– is hydrogen sulfate

Binary Ionic Compounds
Two elements (one metal and one nonmetal;
without transition metal)
Naming: Use name of metal, then put in name
of nonmetal with ‘ide’ as the suffix.

Examples:
NaCl
sodium chloride
ZnI2
zinc iodide

Binary Ionic Compounds
Two elements (one metal and one nonmetal;
with transition metal)
Naming: Use name of metal, then put in name
of nonmetal with ‘ide’ as the suffix.
**Difference** Must input Roman Numerals
Mn2+ + 2 Cl-  MnCl2
Manganese (II) Chloride
Transition Metals
Elements that can have more than one possible charge MUST have
a Roman Numeral to indicate the charge on the individual ion.
1+ or 2+
Cu+, Cu2+
2+ or 3+
Fe2+, Fe3+
copper(I) ion iron(II) ion
copper (II) ion iron(III) ion
Transition metals (except Ag, Zn, Cd, and Al)
require a Roman Numeral.

Hydroxide
Naming Ternary Compounds
Contains at least 3 elements
There MUST be at least one polyatomic ion
(it helps to circle the ions)
