    The formula that would represent an ionic compound that is composed of calcium and iodide ions is CaI2

    Explanation

    Ionic compound CaI₂ is formed when Calcium form cation (a positively charged ion) by losing 2 electrons while two iodine atoms form anion (a negatively charged ion) by gaining one electron each.

    When writing down formula of ionic compound, the formula of cation is written first followed by anion formula. therefore Ca is written first followed by I.

    The numeric subscript 2 after I (iodine) indicate that 2 atoms of iodine are involved in bonding.
