Question

if the ionisation potential and electron affinity of an element are 17.92eV and 4.48eV then the electronegativity of the element on pauling scale is​

Answer 1

Explanation:

hey there is answer !!

Dear student,

The Electronegativity according to the Mullikan's scale is given by the formula: Electronegativity = (Ionisation Energy + Electron Affinity)/17.92 The value of ionisation energy = 4.48 eV The value of electron affinity = 2 eV Now, Electronegativity = 17.92 +4.48 = 22.4Regards
