Answer

a TRUE

Explanation

In chemistry, metal ions that can exhibit more than one charge state use Roman numerals in parentheses to indicate their specific charge. This nomenclature helps in identifying the exact ion present in the compound. For instance, iron can form ions with a charge of +2 or +3, which are written as Iron(II) and Iron(III), respectively. The use of Roman numerals immediately following the name of the cation clarifies which ion is present.
