Chapter 8, Problem 8.140QP

Interpretation Introduction

Interpretation: Wavelength of light emitted in a transition from the first excited state to the ground state has to be calculated.

Concept Introduction:

First ionization energy: The ionization energy is the minimum energy required to remove the electron from an isolated atom which is in the gaseous state results to give gaseous ion with one positive charge.

According to Planck’s equation,

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