Multiple choice

In insulators, the energy gap between occupied energy level and unoccupied energy level (conduction band) is _________.

  1. larger than semiconductors

  2. larger than conductors

  3. larger than semiconductors but less than conductors

  4. zero

  5. both 1 and 2

E Correct answer
Explanation

Yes, it is correct. Both the options 1 and 2 are correct. The energy gap is largest in insulators. In insulators, the difference in energy between occupied energy level and unoccupied energy level (conduction band) is higher because of which electrons do not flow from occupied energy band to the next higher unoccupied energy band resulting insulators do not conduct electricity as electrons do not flow.
