Explanation:
Aluminium is the metal which does not corrode when left exposed to air. Also it occurs in nature in the form of its oxide and is used in thermite reaction.
Aluminium does not corrode because a natural layer of aluminium oxide is present on its surface. This layer avoids the contact of aluminium with air, oxygen or moisture.
Hence, aluminium does not get corroded.
