Chapter 11, Problem 113AP

Interpretation Introduction

(a)

Interpretation:

The electronic configuration of the given element by using the symbol of the previous noble gas 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 that is moving freely in an orbital is given by the electronic configuration of that atom.

Answer to Problem 113AP

The electronic configuration of the given element, titanium, is $\left[\text{Ar}\right]3{\text{d}}^{2}4{\text{s}}^2$.

Explanation of Solution

The electronic configuration of titanium that has atomic number equal to $\text{Z}=22$ is shown as,

$\left[\text{Ar}\right]3{\text{d}}^{2}4{\text{s}}^2$

This electronic configuration is shown by using the symbol of the noble gas, argon $\left[\text{Ar}\right]$, which has atomic number equal to $18$. The total number of core electrons, that is, $18$ possessed by titanium is shown by the symbol of argon $\left[\text{Ar}\right]$. The electronic configuration of argon is $1{\text{s}}^{2}2{\text{s}}^{2}2{\text{p}}^{6}3{\text{s}}^{2}3{\text{p}}^6$.
