Chapter 11, Problem 126CP

Interpretation Introduction

Interpretation:

On the basis of the electronic configuration, the three given elements are to be identified and their appropriate values of first ionization energies and atomic radii are to be matched.

Concept Introduction:

The distribution of the electrons that exists in the atomic orbital of an atom is collectively known as electronic configuration. The description of every electron in an orbital is given by the electronic configuration of that atom.

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.
