Chapter 22, Problem 22.79QP

Interpretation Introduction

Interpretation: The electronic configuration for ${\text{Gd}}^{3+}$ and the number of unpaired electrons present is to be stated.

Concept introduction: Gadolinium is a metal having an atomic number $64$. It is a silvery-white metal which is ductile and malleable. ${\text{Gd}}^{3+}$ chelates are used in magnetic resonance imaging (MRI) because their magnetic moment is high due to the presence of seven unpaired electrons and it is paramagnetic in nature.

To determine: The electronic configuration for ${\text{Gd}}^{3+}$ and the number of unpaired electrons present.
