    Solution:

    The above statement is true.
    Aluminium metal is reasonably reactive yet used to make utensils. Aluminium is a reactive metal. It forms a layer of Al2O3 or aluminium oxide on coming in contact with moist air. This layer of oxide prevents the utensils from further corrosion. Thus aluminium is a metal which is highly resistant to corrosion. Furthermore, this alumina layer can be dyed to give the utensils a lucrative shine and colour. Aluminium is a ductile metal, and it has a high melting point as well as good thermal conductivity.
