उत्तर
Aluminium is a highly reactive metal. It reacts with oxygen in moist air to form a thin, dull layer of aluminium oxide on its surface. This layer tarnishes the metal, causing it to lose its initial shine. However, this oxide layer acts as a protective barrier, preventing further corrosion of the inner aluminium.
