Naming Ionic Compounds
1. Cation (metal) always goes first.
2. Anion (nonmetal) goes second.
3. Anion (nonmetal) gets an -IDE ending.

Naming Polyatomic Ionic Compounds:
: An ion that contains more than one atom
covalently bonded together. (on the back of your PT)
1. Find the charge of each part. (Back of periodic table)
2. Determine how many of each ion is necessary to create a neutral compound.
3. If you need more than one of the polyatomic ions, put parentheses around it and
add a subscript.
4. The cation is still named first.
5. Polyatomic ion uses its name, may not end in -IDE.

Determine the possible charge on each ion. (Roman numeral)
Determine how many of each you need to create a neutral compound.
The charge is written in Roman numerals behind the metal’s name.
The anion is still written the same way with -IDE at the end (or name from back).
