What Is The Chemical Formula For Iodine And Calcium Ionic Compound?

The chemical formula for the ionic compound formed between iodine and calcium is CaI2. This is because iodine (I) has a charge of -1, and calcium (Ca) has a charge of +2. In order to balance the charges and form a neutral compound, two iodine ions are required for every one calcium ion, resulting in the formula CaI2.
