Vedclass · Answer

(B) In insulators,the energy gap between the valence band and the conduction band is very large (typically $> 3 \ eV$). At absolute zero temperature,the valence band is completely filled with electrons,and the conduction band is completely empty. Due to the large energy gap,electrons cannot jump from the valence band to the conduction band even at room temperature,which is why insulators do not conduct electricity.
