How does this suggest the charge of the hypochlorite ion in the compound is calcium hypochlorite?

The calcium ion has a charge of 2+ (Ca2+)

hypochlorite has a charge of 1-. Calcium ions have a charge of 2+, when they form a molecule, you get CaClO2, where the subscript of CLO indicates the charge of the cation in this case calcium.

Hypochlorite has a formula of Ca(ClO)2, ClO has an overall charge of +1, given there are two molecules the overall charge is +2. Calcium ion also has a charge of +2 on its own. Therefore the Calcium ion charge is equal to the hypochlorite ion molecule charge.

Calcium hypochlorite formula is Ca(ClO)2, Calcium is having +2 charge. Therefore two hypochlorite is having -2 charge. Here two hypochloite ions sharing -2 charge. Each hypochlorite ion is having -1 charge.

Calcium hypochlorite which has a chemical formula Ca(ClO)2, so the overall charge of the compound is 0 and Ca2+ has a charge of +2. In order to have an overall charge of 0, (ClO)2 has to be -2 to balance the charge of Ca2+. Therefore, ClO has a charge of -1 as there are two ClO ions.

Calcium hypochlorite is Ca(ClO)2. If Ca has charge 2+ this means the hypochlorite ion has charge -1, so that two such ions combine with the Ca2+.In the hypochlorite ion a covalent bond between Cl and O fills the Cl valence shell, and leaves one electron lacking in O's valence shell. So an extra electron stabilises the pair to form the ion with single negative charge.
