The energy gap between conductionband and valence band is of the order of 0.07 eV. It is a/anA. insulatorB. conductorC. semiconductorD. alloy

Answer» Correct Answer - B
The energy gap between conduction band and valency band is 0.07 eV, which is very small. Therefore, the electrons can go very easily from valence band to conduction band after gaining a little energy. Hence the material is a conductor.
