Chapter 6, Problem 79QP

Interpretation Introduction

Interpretation:

The maximum number of electronsthat can be accommodated in thesubshells $3s$, $3d$, $4p$, $4f$, and $5f$ is to be determined.

Concept Introduction:

An atom has a positivelycharged nucleus, which is surrounded by negativelycharged electrons. The electrons revolve around the nucleus in their orbitals (or shells). Each orbital has subshells.

The arrangement of electrons in the orbitals of an atom is calledelectronic configuration. It is written with the help of quantum numbers.

Every electron occupies orbitals in the increasing order of their energies.
