Chapter 11, Problem 24E

Interpretation Introduction

Interpretation:

The number of orbitals in an atom with $n=3$ is to be calculated.

Concept introduction:

The principal energy levels are identified by the principal quantum number, $n$. In quantum mechanical model, for each principal energy level there are one or more sublevels. These sublevels are, $s,p,d,$ and $f$. A specific sublevel is identified by both the principal energy level and sublevel.
