Pauling scale
Linus Pauling: Phenomenon of electronegativity
Relative electronegativities of two atoms in a molecule.
$EN\left(X\right)-EN\left(Y\right)=$ $0.102\left(△1/2\right).1$
$0.02$ is conversion factor between kJ and eV is:

Answer 1

$|X_A-X_B|=0\cdot 102\times {\left(\Delta E\right)}^{\frac{1}{2}}$

Where $\Delta E=$difference of $I.E$ and $E.A$ in unit of $kJ{mol}^{-1}$

and $0.102$ is used to convert energy from $kJ{mol}^{-1}$ to $eV$ as per pauling direction$.$
