Chapter 8, Problem 8.7QE

Interpretation Introduction

Interpretation:

The different values of ionization energy for an atom have to be determined. Also, the factor that determines this number 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 remove the first electron from the neutral atom is called the first ionization energy, denoted by $I_1$. The energy required to remove 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.
