Chapter 5, Problem 109QRT

Interpretation Introduction

Interpretation:

The increasing order of first ionization energy of given elements $\text{Zn,}\text{Ca,}{\text{Ca}}^{\text{2+}}\text{,}\text{and}{\text{Cl}}^{\text{-}}$ has to be ranked and explained.

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,

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