In a chemical formula, more than one polyatomic ion is indicated by using parentheses around the ion and then placing a subscript outside the parentheses to denote the number of that ion present. For example, in the case of calcium nitrate, which contains two nitrate ions (NO₃⁻), the formula is written as Ca(NO₃)₂. This notation clarifies that there are two nitrate ions associated with each calcium ion in the compound.
