Chapter 7, Problem 129AP

Interpretation Introduction

Interpretation:

The ionization energy of potassium is to be determined and the ionization energy corresponding to the electron in the valence shell is to be explained.

Concept introduction:

The ionization energy of an atom is calculated by using the expression given below.

$\text{h}\nu =\text{IE}+\frac{1}{2}\text{m}{\text{u}}^2$,

Here, $\nu$ is the frequency of the UV photon, and $\text{m }\text{and}\text{ u}$

are the mass and velocity of the ejected electron, respectively.
