Chemistry- Naming Ionic Compounds

Title Ionic Compounds with the Stock Naming System or the Old Way

How do you name multivalent cations in the Old Way?

Multivalent cations are named in the Old Way by adding the suffix -ous if the cation is greater than the Anion, or -ic if it is less than the Anion. The Anion follows the cation with the suffix -ide.

How do you name multivalent cations in the Stock Naming System?

Multivalent cations are named in the Stock Naming system by placing the Roman numeral for the element’s Oxidation state after the cation. Place the Anion next with the suffix -ide.
