Chapter 6, Problem 6.68SP

Interpretation Introduction

Interpretation:

Among ${\text{Na}}^{+}$ or $\text{Na}$, species with more negative electron affinity should be determined. Also, among $\text{Na}$ or $\text{Cl}$, species with more negative electron affinity should be determined.

Concept introduction:

Change in energy after the addition of an electron to a neutral isolated gaseous atom is called electron affinity. It is denoted by $E_{\text{ea}}$. A neutral atom becomes anion after the addition of an electron to it. More negative $E_{\text{ea}}$ indicates a greater tendency to accept an electron and vice-versa.
