Chapter 7, Problem 7.128AP

(a)

Interpretation Introduction

Interpretation: The emission of $2s$ electron on absorption of X-ray by an atom that leads to the formation of hole that can be filled by electron from $2p$ orbital and the energy lost during this transition is given. Various questions based on this transition are to be answered.

Concept introduction: The relation between energy, wavelength and speed of light is given as,

$\Delta E=h\frac{c}{\lambda }$

Where,

• $h$ is the Planck’s constant $\left(6.626\times {10}^{-34}\text{Js}\right)$.
• $\lambda$ is the wavelength of the light.
• $c$ is the speed of the light $\left(3\times {10}^8\text{m}/\text{s}\right)$.
• $\Delta E$ is the energy difference.

To determine: The nature of wavelength of the photon along the fourth period when transition occurs from $2\text{p}$ orbital to $2\text{s}$ orbitals.
