Chapter 6, Problem 6.57SP

Interpretation Introduction

Interpretation:

The element with the smallest and the largest ionization energy in the periodic table should be determined.

Concept introduction:

Ionization energy is the amount of energy needed to eliminate an electron from an isolated, neutral gaseous atom. It is denoted by $E_{\text{i}}$. The energy needed to eliminate the first electron from a neutral atom is known as the first ionization energy, represented by $E_{\text{i1}}$. The energy needed to eliminate an electron from monoatomic cation is second ionization energy $\left(E_{\text{i2}}\right)$.
