Explanation:
Detailed explanation-1: -The overall charge for the ionic compound must be neutral, which means the sum of the charges from the cations and anions should add up to zero. We can use this rule to figure out the formula of an ionic compound when we know the charge on the anion and the cation.
Detailed explanation-2: -In every ionic compound, the total number of positive charges of the cations equals the total number of negative charges of the anions. Thus, ionic compounds are electrically neutral overall, even though they contain positive and negative ions.
Detailed explanation-3: -Each ion has a single charge, one positive and one negative, so we need only one ion of each to balance the overall charge.
