Question

what is the meaning of oxides...

Answer 1

any thing which has reacted with oxygen

Answer 2

An oxide is a chemical compound that contains at least one oxygen atom and one other element in its chemical formula. "Oxide" itself is the di - anion of oxygen, an O2– atom. Metal oxides thus typically contain an anion of oxygen in the oxidation state of −2

For example, aluminium foil develops a thin skin of Al2O3 - ALUMINIUM OXIDE (called a passivisation layer) that protects the foil from further corrosion.
