• either way is fine
• polyatomic ions first

The first step in naming an ionic compound is always...

• Naming the anion (non-metal)

• Changing the ending to -ide

• Naming the cation (metal)

• Writing the cation charge

When naming ionic compounds with transition metals you need to include roman numerals to show the _____ of the metal..
