Chapter 11, Problem 108AP

Interpretation Introduction

(a)

Interpretation:

The electronic configuration of the given element is to be stated.

Concept Introduction:

The distribution of the electrons that exists in the atomic orbital of an atom is collectively known as electronic configuration. The description of every electron in an orbital is given by the electronic configuration of that atom.

Answer to Problem 108AP

The electronic configuration of the bromine with $\text{Z}=\text{35}$ is $1{\text{s}}^{2}2{\text{s}}^{2}2{\text{p}}^{6}3{\text{s}}^{2}3{\text{p}}^{6}3{\text{d}}^{10}4{\text{s}}^{2}4{\text{p}}^5$.

Explanation of Solution

The electronic configuration generally represents the arrangement of electrons in their orbitals in ground state. The electrons are filled while writing configuration in a way such that all the electrons are filled in the orbitals of a shell and then moves to another shell. Hence, the electrons are filled in orbitals according to their increasing energies. The electronic configuration of the bromine with $\text{Z}=\text{35}$ is $1{\text{s}}^{2}2{\text{s}}^{2}2{\text{p}}^{6}3{\text{s}}^{2}3{\text{p}}^{6}3{\text{d}}^{10}4{\text{s}}^{2}4{\text{p}}^5$.
