Question

Statement: In an insulator, the band gap is small.

State whether the given statement is true or false.

• A. True
• B. False

Answer 1

The correct option is B False

In an insulator, the bandgap is large. More energy is required to promote electrons from valence band to conduction band. This energy is not available. The electrons remain in the valence band and cannot move freely. Hence, insulators are bad conductors of heat and electricity.

Hence, the given statement is $\text{false}$
