Oxides. Oxides are compounds that contain one or more oxygen atoms and one or more other atoms. Oxide compounds make up a large proportion of the earth’s crustnearly all metals naturally occur as minerals in oxide and compound forms which require processing and treatment to obtain the pure metal. The electronegativity of oxygen allows it

A basic oxide is an oxide which when combined with water gives off a base. When a substance reacts chemically both as a base or acid it termed as an amphoteric solution. Neutral Oxide is one which neither has an acidic characteristic or a basic one. Metal Oxides have an oxidation number of 2 and generally comprise of an oxygen anion.
