Question

What is the relation between Mulliken and Pauling Scale for measurement electronegativity?

Answer 1

According to Mullikan scale:

Electronegativity = Ionisation enthalpy + Electron gain enthalpy / 2
When IE and electron gain enthalpy are expressed in eV.
Electronegativity = Ionisation enthalpy + Electron gain enthalpy / 540 When ionization enthalpy and electron gain enthalpy are expressed in kJ/mol.
χ_pauling = χ_mullikan/2.8
χ_pauling = Ionisation enthalpy + Electron gain enthalpy /5.6
