Answer 2

Answer:

a counductor

Explanation:

They are bad conductors of heat and electricity. The space between valence band and conduction band is relatively more. Hence, more energy is required to promote electrons from valence band to conduction band. This amount of energy is not available. Electrons remain in valence band. They cannot move freely. Examples of insulators include glass, rubber, polythene, plastic, wood and diamond.
