    I believe the correct answer from the choices listed above is the first option. The naming rule that would apply to CaCO3 is should be metal cation + nonmetal anion (ide). The naming would be written as Calcium Carbonate. Hope this answers the question.

    Metal (Ca) Polyatomic anion (CO3). You do not need to use the roman numeral because Ca is in group 1. The answer is metal + polyatomic or Calcium Carbonate
