Chapter 7, Problem 7.114QP

(a)

Interpretation Introduction

Interpretation: From the given electronic configurations, those with excited electronic configuration are to be stated.

Concept introduction: Electronic configuration determines the electron distribution in an atom or a molecule. The entire periodic table is based upon the distribution of electrons in the atom. When the electron gets jumped to higher energy level or orbital after absorption of energy then it is called its excited state. The ground state corresponds to lowest energy state.

To determine: If $\left[\text{Ne}\right]{\text{3s}}^{\text{2}}{\text{3p}}^{\text{1}}$ represents an excited state.

(b)

Interpretation Introduction

To determine: If $\left[\text{Ar}\right]{\text{3d}}^{\text{10}}{\text{4s}}^{\text{1}}{\text{4p}}^{\text{2}}$ represents an excited state.

(c)

Interpretation Introduction

To determine: If $\left[\text{Kr}\right]{\text{4d}}^{\text{10}}{\text{5s}}^{\text{1}}{\text{5p}}^{\text{1}}$ represents an excited state.

(d)

Interpretation Introduction

To determine: If $\left[\text{Ne}\right]{\text{3s}}^{\text{2}}{\text{3p}}^{\text{6}}{\text{4s}}^{\text{1}}$ represents an excited state.
