The net charge of Ca is +2
The formula for calcium sulfide is CaS because calcium, as an alkali earth metal, has a 2+ charge and sulfur, as a nonmetal, has a 2- charge. Therefore, they combine in a 1:1 ratio to balance the charges, resulting in the formula CaS.
The ionic compound formed between calcium and sulfur is calcium sulfide, with the chemical formula CaS. In this compound, calcium has a 2+ charge and sulfur has a 2- charge, resulting in a neutral combination.
The chemical formula starts out with the two ions, the calcium and sulfide ions. Calcium's ion is Ca2+, while the sulfide ion is S2-. Because the net ionic charge of a compound is zero, only one of each atom is needed to create calcium sulfide, which will be CaS.

Ja Cas is heel lief. ;)
Yes, CaS is the chemical formula for calcium sulfide.
CaS is Calcium Sulfide
