Chapter 6, Problem 86QP

Interpretation Introduction

Interpretation:

The orbital diagrams violating Pauli exclusion principle, and Hund’s rule are to be determined.

Concept introduction:

According to Pauli exclusion principle, no two electrons in an atom can have the same set of quantum numbers. Therefore, two electrons in the same orbital have opposite spin that is the different value of electron spin quantum number.

According to Hund’s rule, an electron can occupy the same orbital in a subshell only if all the orbitals of that subshell are singly occupied by an electron. It also states that electrons in the singly occupied orbital should have the same spin (generally, spin-up) to maximize the total spin.
