Chapter 21, Problem 83CWP

(a)

Interpretation Introduction

Interpretation: The species with correct electronic configuration are to be identified.

Concept introduction: Electronic configuration describes the number of electrons in an element and how all the electrons are arranged in each energy level. It is also useful in describing the chemical bonds by which the atoms are held together.

To determine: If the given electronic configuration of $\text{Cu}$ is correct.
