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.
In calcium sulfide (CaS), calcium (Ca) has a charge of +2, as it is an alkaline earth metal that typically loses two electrons. Sulfide (S) has a charge of -2, as it gains two electrons to achieve a stable electron configuration. Therefore, the overall charge balance in CaS is neutral, with one Ca^2+ ion combining with one S^2- ion.
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.
