Chapter 8, Problem 8.28PAE

Interpretation Introduction

Interpretation:

“How the combination of atomic orbitals gives rise to bands in the limit of large number of atoms” should be described.

Concept Introduction:

Electrons in an atom are arranged in orbitals. Each orbital has a specific energy level. When an electron jumps from a lower energy orbital to a higher energy orbital then it absorbs energy. When it jumps from a higher energy orbital to a lower energy orbital then it releases the excess energy in the form of light bands.
