Chapter 2, Problem 2.114CHP

Interpretation Introduction

Interpretation:

The values of ${\text{Z}}_{\text{eff}}$ for the highest energy electrons in potassium and krypton has to be calculated.

Concept introduction:

Effective nuclear charge:

The value of effective nuclear charge is calculated by the following equation

$\begin{array}{l}{\text{Z}}_{\text{eff}}\text{=}\sqrt{\frac{\left(\text{E}\right)\left({\text{n}}^{\text{2}}\right)}{\text{1312}\text{kJ/mol}}}\\ \text{where,}\\ {\text{Z}}_{\text{eff}}\text{-}\text{effective}\text{nuclear}\text{charge}\\ \text{E}\text{-}\text{energy}\text{necessary}\text{to}\text{remove}\text{an}\text{electron}\text{from}\text{an}\text{atom}\\ \text{n}\text{-}\text{principal}\text{quantum}\text{number}\end{array}$
