Chapter 8, Problem 8.97QP

Interpretation Introduction

Interpretation:

Photon wavelength (in nanometers) corresponding to the electron affinity for chlorine has to be calculated and the region of the electromagnetic spectrum which the wavelength fall has to be identified.

Concept Introduction:

Electron Affinity: It is the energy change taking place when one electron is added to an atom which is neutral in its gaseous state forming an anion.

According to Planck’s equation,

$\begin{array}{c}\text{E}\text{=}\frac{\text{hc}}{\text{λ}}\\ \text{where, h}\text{=}\text{Planck's}\text{constant}\\ \text{λ}\text{=}\text{wavelength}\\ \text{c}\text{=}\text{speed}\end{array}$

Electromagnetic radiations are a type of energy surrounding us. They are of different types like radio waves, IR, UV, X-ray etc.

Ultraviolet radiation lies between $200\text{nm}$ to $400\text{nm}$
