Chapter 5, Problem 89QRT

Interpretation Introduction

Interpretation:

From the given elements $\text{Si,}\text{Na,}\text{P,}\text{and}\text{Mg}$, elements having greatest difference between the first and second ionization energy have to be identified.

Concept Introduction:

Ionization energy: It is the energy needed to remove an electron from that atom in gas phase.  For a gaseous sodium atom, the ionization process is given as,

    ${\text{Na}}_{\text{(g)}}\underset{}{\overset{}{\to }}{\text{Na}}^{\text{+}}{}_{\text{(g)}}\text{+}{\text{e}}^{\text{-}}$
