The electronegativity of that atom on Mulliken scale is given by EN=(IE + EA/2) and EA=-Eeg Ionisation energy and electron affinity must be in ev/atom.

Q. Electron gain enthalpy and ionisation energy of an atom are $- a$ and $+ b e V$ respectively. The electronegativity of that atom on Mulliken scale is given by :

a – b

$\frac{b - a}{2}$

a + b

$\frac{a + b}{2}$

The electronegativity of that atom on Mulliken scale is given by
$EN = \frac{I E + E A}{2}$ and $E A = - E_{e g}$
Ionisation energy and electron affinity must be in ev/atom.

Q. Electron gain enthalpy and ionisation energy of an atom are −a and +beV respectively. The electronegativity of that atom on Mulliken scale is given by :
