Chapter 8, Problem 8.116QP

Interpretation Introduction

Interpretation:

The amount of energy evolved from the given atom has to be calculated.

Concept introduction:

The amount of energy which is released when an additional electron enters the outer orbital of an isolated neutral atom to form a negative ion.

$\text{Atom}\left(\text{g}\right)\text{+ Electron}\left(\text{g}\right)\to \text{Negative ion}\left(\text{g}\right)\text{+ Energy}$

The greater the energy released in the process of taking up the extra electron, the greater will be the electron affinity.
