E. N of the element A is

{E_1}

and I.E is

{E_2}

. Hence, E. A will be

View answer and explanation

Correct option: A

2{E_1} - {E_2}

Option A (

2{E_1} - {E_2}

) is correct. Electron affinity (E.A) can be related to electronegativity (E.N) and ionization energy (I.E) using Mulliken's formula: E.N = (I.E + E.A)/2. Rearranging, E.A = 2*E.N - I.E.
