Ionisation potential 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's equation
`chi = (IP + EA)/(5.6)` when both `IP` and `EA` are taken in `eV`
`chi_(F) = (17.42 + 3.45)/(5.6) = 3.726`
