Ionization energy of atoms A and B are 350 and 250 kcal/mole respectively. The electron affinity of these atoms are 70 kcal/mol and 90 kcal/mol respectively then:

Electron cloud is more abstracted to those atoms having more Ionization energy. Hence electron cloud is more attracted by atom A.  $IE=-EA.$ So that atoms having more I.E has high E.A.

$$\begin{gathered} E{N}_A\alpha 350+70 \\ E{N}_B\alpha 250+90 \\ \therefore {\text{EN}}_{\text{A}}>{\text{EN}}_{\text{B}} \end{gathered}$$
