Which of the following are correct insulators-The valence band is partially filled with electrons-The conduction band is partially filled with electrons-The conduction band is partially filled with electrons and valence band is empty-The conduction band is empty and the valence band is filled with electrons-

Question

Toppr Admin · Accepted Answer

In insulators- the electrons are very tightly bound to the nucleus- At a room temperature- thermal energy is not enough to push electrons into conduction band- The energy band gap is very high- Thus the conduction band is empty and the valence-xA0-band is filled with electrons-

In insulators, the electrons are very tightly bound to the nucleus. At a room temperature, thermal energy is not enough to push electrons into conduction band. The energy band gap is very high. Thus the conduction band is empty and the valence band is filled with electrons.
