The American chemist Robert S. Mulliken suggested a different definition for the electronegativity (EN) of an element, given by
\(\mathrm{EN}=\frac{\mathrm{IE}+\mathrm{EA}}{2}\)
where IE is the first ionization energy and EA the electron affinity of the element. Calculate the electronegativities of O, F, and Cl using the above equation. Compare the electronegativities of these elements on the Mulliken and Pauling scale. (To convert to the Pauling scale, divide each EN value by 230 kJ/mol.)

Compare the electronegativities of these elements on the Mulliken and Pauling scale. (To convert to the Pauling scale, divide each EN value by 230 kJ/mol.)
ANSWER:Step 1 of 4
Electronegativity of the element can be calculated by following formulae.
Here, IE is the Ionization energy of the element and EA is the electron affinity of the element.
