Answer:
Calcium Sulfide. The Lewis Structure shows it as CaS
Explanation:
Calcium is considered a metal on the periodic table, while sulfur is a non-metal. Calcium has a 2+ ionic charge while sulfur has a 2- ionic charge. Since you want a charge of 0, the Calcium ionic charge of 2+ and the sulfur ionic charge of 2- cancel out, since 2+(-2)= 0
