Alloys and compounds of zinc have been known since at least 500 B.C. But zinc metal was not known or used until much later. The reason is that zinc boils away or vaporizes easily when heated. Any effort to release zinc from its compounds also causes the metal to evaporate into the air. Zinc was probably known in Asia before it was discovered in ...

Compounds of Zinc 1. Zinc Oxide. Zinc oxide has the molecular formula ZnO and is the most common zinc oxide. Heating ZnS in the air or thermal decomposition of zinc carbonate produce ZnO. At room temperature, it is white. The loss of oxygen from the ZnO lattice causes ZnO to turn yellow, resulting in non-stoichiometric compositions like Zn1+xO.
