Explanation:
Zinc is used in alloys with copper to create a harder metal known as brass. In galvanization, zinc coats iron by oxidizing to form a protective layer of zinc oxide (ZnO) that protects the iron from oxidation. Zinc oxide is much safer than lead oxide, and it is often used in white paint.
