    The energy gap between conduction band and valence band is of the order of 0.07 eV. It is a/an

    A) insulator                             

    B) conductor

    C) semiconductor                 

    D) alloy

    Correct Answer: B

    Solution :

    The energy gap between conduction band and valence band is 0.07 eV, which is very small. So, the electrons very easily go from valence band to conduction band by gaining little energy. Hence, the material is a conductor.
