Chapter 21, Problem 21.67SP

Interpretation Introduction

Interpretation:

Draw a molecular orbital energy-level diagram that demonstrates the population of the 4s band in pure potassium metal.

Concept introduction:

• There are two theoretical models for bonding in metals which are the electron-sea model and the molecular orbital theory.
• Molecular orbital theory is the combination of atomic orbitals of individual atoms to form molecular orbitals.
• The number of molecular orbitals formed is the same as the number of atomic orbitals combined.

To classify: An image of the 4s band of potassium.
