Question

Quizplus · Accepted Answer

The formula for ionic compounds is determined by balancing the charges of the ions. Calcium is a group 2 element with a 2+ charge, while sulfur is a group 16 element with a 2- charge. To balance the charges, one calcium ion (Ca2+) combines with one sulfur ion (S2-) to form CaS. Therefore, the correct answer is A, CaS.
