Jamal is working with three ionic compounds: sodium chloride, calcium sulfide, and barium oxide. his teacher asks him which are the positive ions in each compound. what should jamal’s answer be? sodium, calcium, and barium barium, sulfur, and oxygen calcium, barium, and chlorine chlorine, sulfur, and oxygen

Option (a) is the correct answer.

Explanation:

An ion who is positively charged is known as a cation. Any specie that loses electrons will acquire a positive charge. Therefore, it becomes a cation.

In the given compounds sodium chloride, calcium sulfide, and barium oxide we can conclude that sodium, calcium and barium are the cations as their ions are positively charged.
