Chapter 8, Problem 8C.10BE

Interpretation Introduction

Interpretation:

The possible atomic terms for the electronic configuration $n{\text{p}}^{1}n{\text{d}}^1$ have to be stated.  The atomic term which expected to lie lowest in energy among the corresponding atomic terms has to be identified.

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,

  ${}^{2S+1}{L}_J$
