Electron gain enthalpy is F is less negative than Cl Why ?

1.	Electron gain enthalpy is F is less negative than Cl Why ?
Answer» Solution :When an electron is added to F, the added electron to the L shell (n=2). As the .L. shell possess smaller region of space, the added electron feels significant repulsion from the other ELECTRONS present in this level. E.A of F = -328 KJ `MOL e^(-1)` E.A of CI=-349 KJ `mol e^(-1)`
