Ionisation paotential and electron affin...

Ionisation paotential and electron affinity of fluorine are `17.42` and `3.45eV` respectively .Calculate the electronegativity of fluorine on Mulliken scale and Pauling scale .

Text Solution

Verified by Experts

According to Mulliken equation ,
` X =(IP +EA)/(2)` , When both `IP` and `EA` are taken in `eV`.
`(X_F)_M = (17.42 +3.45)/(2) =10.435`
`(X_F)_P= (10.435)/(2.8) =3.726 [or (Z_F)_P =(IP+EA)/(5.6)]`
