Chapter 9, Problem 25PE

Interpretation Introduction

Interpretation:

For calcium metal, the orbitals, which form valence band and conduction band are to be discussed.

Concept Introduction:

With exceptions, metals are good conductors of electricity while nonmetals are good insulators.

Conduction of electricity is explained on the basis of energy bands. A solid is composed of energy levels that are spaced closely and are formed by joining or overlapping of atomic orbitals of similar energy levels.
