Chapter 6, Problem 58A

Interpretation Introduction

Interpretation:

The term ionization energy needs to be explained.

Concept introduction:

Ionization energy can be defined as the measure of amount of energy needed to remove an electron form an atom or an ion.

Explanation of Solution

Ionization energy can be defined as the measure of amount of energy needed to extract an electron form an atom or an ion from is valence shell. The energy required to remove the first electron is termed as first ionization energy. Similarly, the energy required to remove the second electron is termed as second ionization energy. For example, the first ionization energy of Lithium is $\text{8}\text{.64}\text{×}{\text{10}}^{\text{-19}}\text{J}$. If the valence electronic configuration for an element is stable that is half-filled or full-filled, the ionization energy will be high.
