Chapter 7.9, Problem 13PE

Interpretation Introduction

Interpretation: The electronic configurations of manganese atom and ions ${\text{Mn}}^{\text{3+}}$ and ${\text{Mn}}^{\text{4+}}$ is to be stated.

Concept introduction: The electronic configuration of atoms follows three rules Hund’s rule, Pauli Exclusion Principle and Aufbau principle. According to Aufbau principle, the orbitals with lower energy level are filled first then orbital with higher energy.

To determine: The electronic configurations of manganese atom and ions ${\text{Mn}}^{\text{3+}}$ and ${\text{Mn}}^{\text{4+}}$.
