Question

In the case of metals, the valence and conduction bands ______.

Options

• do not overlap, energy gap = 0

• overlap, energy gap = 0

• do not overlap, energy gap is small

• do not overlap, energy gap is large

Answer 1

In the case of metals, the valence and conduction bands overlap, energy gap = 0.

Explanation:

In conductors, the energy gap is absent, or in other words, the conduction band and the valence band overlap.
