Explanation:

Step1: Identify poly - atomic ions and metal ions

For naming or writing formulas of polyatomic compounds, we first identify the metal ion and the poly - atomic ion.

Step2: Apply charge - balance rule

The total positive charge from metal ions must equal the total negative charge from poly - atomic ions.
