Answer

Explanation:

Step1: Determine calcium ion charge

Calcium in group 2 loses 2 electrons, forming $Ca^{2 + }$.

Step2: Determine chlorine ion charge

Chlorine in group 17 gains 1 electron, forming $Cl^{-}$.

Step3: Balance charges

To balance the +2 charge of calcium, we need 2 chloride ions. So the formula is $CaCl_{2}$.

Answer:

$CaCl_{2}$
