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

a - b

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

a + b

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

$EN = \frac{IE + E A}{2} and E A = - E_{g a}$

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

a - b

2b−a​

a + b

2a+b​

EN=2IE+EA⁡​andE⁡A⁡=−E⁡ga​

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

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

$EN = \frac{IE + E A}{2} and E A = - E_{g a}$
