Chapter 15, Problem 15.20E

Interpretation Introduction

Interpretation:

The total number of states in an atom which has $d^3$ electron configuration for its valence subshell is to be predicted.

Concept introduction:

A term symbol describes the orbital, spin, and total angular momenta of an electronic state. The symbol $L$ represents the vector sum of orbital angular momentum. The symbol $S$ represents the vector sum of spin angular momentum. The symbol $J$ represents the total angular momentum. Therefore, the term symbol is represented as given below.

${}^{2S+1}{L}_J$
