Using Mullikens formula, calculate a value for the electronegativity of oxygen. Convert the result to a value

Question:

Using Mulliken€™s formula, calculate a value for the electronegativity of oxygen. Convert the result to a value on Pauling€™s scale. See Problem 9.139.
Problem 9.139
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.
