Chapter 2, Problem 2.68P

Interpretation Introduction

(a)

Interpretation:

Ground-state electronic configuration of $\text{Mg,}{\text{Mg}}^{+},{\text{Mg}}^{2+}\text{and}{\text{Mg}}^{3+}$ is to be stated.

Concept Introduction:

Electron configuration is the distribution of electron in different energy level orbits. Ionization energy is measure of how difficult it is to remove the most loosely held electron from an atom in the gaseous state, higher the difficulty in removing the atom; higher will be the ionization energy.

Interpretation Introduction

(b)

Interpretation:

The reason for the large increase in ionization energy for removal of the third electron from the Mg atom is to be explained.

Concept Introduction:

Ionization energy is measure of how difficult it is to remove the most loosely held electron from an atom in the gaseous state, higher the difficulty in removing the atom; higher will be the ionization energy.
