## Using Mulliken’s formula, calculate a value for the electronegativity of chlorine. Use values of the ionization energy from Figure 8.18 and values of the electron affinity from Table 8.4. Divide this result (in kJ/mol) by 230 to get a value comparable to Pauling’s scale.

Expert Solution
Interpretation Introduction

Interpretation:

The electronegativity of Chlorine, the value of the ionization energy and the electron affinity both are divided the values by 230 to get a value that values compared to Pauling’s scale has to be calculated.

Concept introduction:

Pauling’s scale is based on an empirical relation among the energy of a bond and the electronegativities of bonded atoms.

EA-B>EA-A×EB-B

Mulliken’s Scale:

According to this method electronegativity could be regarded as the average of the ionization energy and electron affinity of an atom

Electronegativity=I.E+E.A2

### Explanation of Solution

The electronegativity of Chlorine is calculated

X=I.E+E.A2=[1251+349]kJ/mol2=800.0kJ/mol

800
