Chapter 8, Problem 8C.9BE

Interpretation Introduction

Interpretation:

The possible values of the spin quantum number $S$ and $M_S$ for the ${\text{V}}^{2+}$ ion have to be stated.

Concept Introduction:

The quantum number $s$ is used to represents the spin angular momentum of a particle.  The value of $s$ is a characteristic value of a particle.  The value of $s$ for electron is $\frac{1}{2}$ and all electrons will have the same value of $s$.  The vector sum of spin angular momentum quantum number is known as the total spin quantum number $S$.  The value of $M_S$ goes from $-S$ to $+S$.
