Chapter 6, Problem 74QP

Interpretation Introduction

Interpretation:

The electronic configuration is to be defined, and the roles of Pauli exclusion principle and Hund’s rule in writing electron configuration are to be explained.

Concept introduction:

An atom has anucleus thatis positively charged and is surrounded by negatively charged electrons. The electrons revolve around the nucleus in their orbitals (or shells).

An orbit represents the planar motion of an electron around the nucleus and the electrons in an atom have only quantized values of energy.
