Chapter 6, Problem 6.66SP

Interpretation Introduction

Interpretation:

There remains inter-electronic repulsion at the nucleus of every atom.

Concept introduction:

Electron Affinity: The electron affinity (E) of an element is the energy released when an electron is added to a neutral gaseous atom of it.As in the case of ionization energy the subsequent introduction of second, third etc…… electrons would give rise to second, third etc……. Electron affinity values ( $E_2,E_3$….etc.).

To determine:

The reason behind the positive electron affinity values of approximately all the elements in periodic table.
