Chapter 7, Problem 7.18QE

Interpretation Introduction

Interpretation:

The existence of maximum six electrons in $3p$ subshell has to be explained through Pauli exclusion principle.

Concept Introduction:

Pauli’s exclusion principle defines that for any two electrons, all the four quantum numbers $\left(n,l,m_l,m_s\right)$ can never be equal. In case when two electrons have the same three quantum numbers $n$, $l$, and $m_l$, then fourth quantum number $m_s$ that also represents spin of the electron must be different.
