Chapter 2, Problem 2.35P

Interpretation Introduction

Interpretation: The reason to explain maxima at 4 electrons and minima at 5 electrons in given figure should be explained.

Concept introduction: Electron affinity is defined as amount of energy that is required to remove one electron from negative ion.

  ${\text{A}}^{-}\left(g\right)\to \text{A}\left(g\right)+{\text{e}}^{-}$

Here electron affinity is positive thus reaction is endothermic in nature.
