Chapter 11, Problem 66AE

Interpretation Introduction

Interpretation:

The reason for the highest second ionization energy of lithium than that of the first ionization energy of helium has to be identified.

Concept Introduction:

Ionization energy:

The amount of energy required to remove an electron from the atom is known ionization energy.  If the first electron from outermost orbital is removed then it will be first ionization energy and, if the second electron is removed then it will be second ionization energy.

For example,

$\text{Na}\text{+}\text{Ionization}\text{energy}\stackrel{}{\to }{\text{Na}}^{\text{+}}\text{+}\text{e}$
