∙ 13y ago
When the compound contains an ion with more than one atom in each ion, and the number of such units in a formula unit of the ionic compound is at least 2, parentheses are needed in the formula of the compound. In more conventional naming, parentheses containing a Roman number are often used after the name of a cation to denote its oxidation state, particular for atoms that form more than one stable cation.
