In good conductor, the gap between the valence band and the conduction band is

Options

  1. Ainfinite
  2. Blarge but not infinite
  3. Czero
  4. Dsmall but not zero

Correct answer

C. zero

Step-by-step solution

In a good conductor, the valence band and the conduction band overlap each other. Due to this overlapping, electrons can easily move from the valence band to the conduction band even at absolute zero temperature. Therefore, the energy gap between the valence band and the conduction band is zero. Answer: zero
