Binary Ionic Compounds (only 2 elements form the compound)

- The anion’s (-)name is similar to the elemental name, but the ending of the name has been removed and replaced with “ide.”
- If a metallic element has cations of different charges, the cation’s oxidation number or valence, has to be indicated by Roman numerals in parentheses after its name in writing (the Stock system).
Depending on the elements forming the compound and their properties, we can classify Ionic compounds as:
