Chapter 19, Problem 31QAP

Interpretation Introduction

(a)

Interpretation:

The abbreviated electronic configuration for metal ion ${\text{Cr}}^{3+}$ needs to be determined.

Concept introduction:

A transition metal cation has no outer s-electrons available for bonding, rather the inner d-electrons (in case of 3d transition metal elements) are available for making coordinate bonds with the ligands. Electrons are distributed in the five d-orbitals according to Hund’s rule which results in a maximum number of unpaired electrons. The abbreviated electronic configuration of an element depicts the electronic configuration of the elements by making use of noble gas configuration as they have fully-filled electron shells.
