Oxide

From GAWDAwiki

An oxide is any chemical compound that contains oxygen and one other chemical element. ^[1]

A chemical compound of oxygen with another element. Hydrated (water-including) iron oxide is called rust; it does not cling tightly to the underlying metal, so the oxidation process is progressive and iron easily rusts away.^[2]
