Answer:

Ca²⁺, S⁻²

Explanation:

Calcium (Ca) is a metallic element and belongs to group II of the Periodic Table. So, it can lose 2 electrons to form the positively charged ion Ca²⁺.

Sulfur (S) is a non-metal element, so it has the tendency to gain electrons and to form anions. It accepts two electrons to form the sulfide ion S²⁻.
