Question

The valence band and the conduction band is attached here on overlap well over each other. The substance is

• A. an insulator
• B. a conductor
• C. a semiconductor
• D. None of these

Answer 1

The correct option is B a conductor

Conductivity of a conductor is very high. This is because electrons can easily jump from valence to conduction band in a conductor. This is because the valence and conduction band overlap in case of a conductor.
