Chapter 21, Problem 21.89QP

Interpretation Introduction

Interpretation:

The number of energy levels in the valence band of a single crystal of sodium with a mass of $2.50\text{ mg}$ has to be calculated.

Concept Introduction:

$\text{Number of atoms = }\frac{\text{Given mass}}{\text{Molar mass}}\times \text{Avogadro number}$

To Calculate: The number of energy levels in the valence band of a single crystal of sodium with a mass of $2.50\text{ mg}$
