Chapter 11, Problem 125CP

Interpretation Introduction

Interpretation:

On the basis of comparison of the ionization energies of the given pair of atoms, the atom with the larger ionization energy is to be stated.

Concept Introduction:

The energy that is needed to eliminate an electron from a neutral atom is known as ionization energy.

According to the periodic table, the ionization energy of the elements increases while moving left to right in the period due to decrease in the atomic size. On the other hand, the ionization energy of the elements decreases while going down the group due to increase in the atomic size of the elements.
