Solution

Forbidden gap :

  1. The forbidden gap is the space between the valence band and the conduction band.
  2. The forbidden gap, as the name implies, has no energy and no electrons remain in this band.
  3. If the forbidden energy gap is larger, the electrons in the valence band are tightly bound or firmly attached to the nucleus.
  4. It is in the range of 1.1 eV for silicon.
