Chapter 9, Problem 9A.6E

(a)

Interpretation Introduction

Interpretation:

The element which has higher ionization energy among the pairs has to be given.

Concept Introduction:

Ionization energy is the energy required to remove an electrons from a gaseous atom (or) iron.  The first ionization energy of an atom (or) molecule is the energy required to remove one mole of electrons from one mole of gaseous atoms (or) ions.

The ionization energy and the atomic size of an atom are inversely proportional which means that smaller the size of the higher the ionization energy.

  $\text{Ionization}\text{}\text{}\text{energy}\text{α}\frac{\text{1}}{\text{atomic}\text{size}}$
