Chapter 8, Problem 8.67QE

Interpretation Introduction

Interpretation:

Whether the third ionization energy of aluminium or magnesium is greater has to be determined. Also, the reason for the same has to be explained.

Concept Introduction:

The energy that is needed to remove an electron from the isolated, neutral gaseous atom is known as ionization energy. It is represented by $I$. The energy required to eliminate the first electron from the neutral atom is called the first ionization energy, denoted by $I_1$. The energy required to eliminate the second electron from the monovalent anion is called the second ionization energy, denoted by $I_2$ and so on. Energy is always supplied to the atom so as to remove an electron from it so ionization energies have positive values.
