Metal Oxide
What is Metal Oxide?
A compound formed when a metal combines with oxygen. Metal oxides are generally basic, and most metals occur in the Earth as their oxides or as other compounds, which is why they must be extracted rather than dug up as the element.
This definition is part of the Metals chapter in Cambridge O Level Chemistry.
