Answer

Explanation:

Step1: Recall ionic compound structure

Ionic compounds consist of positive and negative ions. Metals usually form positive ions.

Step2: Identify metals in compounds

In sodium chloride (NaCl), sodium (Na) is a metal. In calcium sulfide (CaS), calcium (Ca) is a metal. In barium oxide (BaO), barium (Ba) is a metal. These metals form positive ions in the compounds.

Answer:

sodium, calcium, and barium
