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)/(5.6)` (where both IP and EA are taken in eV).
`X _(F) = (17.42+3.45)/(5.6) =3.726`
