Question

Which statement explains how the bands in the crystal of a metal are like atomic orbitals?

Answer 1

D

Step-by-step explanation:

They both allow electrons to move from lower energy levels to higher energy levels.

Answer 2

Please provide the choices here.

The similarity of the bands in the crystal of a metal to the atomic orbitals can be explained by the band theory of metals. In an atom, when the electrons get excited, the electrons jumps to a higher orbital so as to reach equilibrium. This is analogous to the electrons in the metals which also jumps to another band once excited by an external energy (e.g. electrical energy).
