6. According to band theory, what are the true nature of the valence band and conduction band in conductors? a) b) c) d) Have an energy gap which depends on the temperature
Answer: a Explanation: Conductors have overlapping energy bands whereas insulators have huge energy band gaps. But semiconductors have relatively small energy band gaps. So, electrons can go from valence band to conduction band easily in conductors and they carry electricity.
