The electron gain enthalpy values of halogens become more negative in the order F>Cl>Br>I.

Comment on this statement


Anjali211: The order is wrong.The correct order of EGE of halogen family is Cl>F>Br>I

electron gain enthalpy corresponds to the amount of energy liberated when an electron is added to the valence shell of a neutral isolated gaseous atom therefore its value is taken as negative.

In a system whenever there is loss of energy ,the change in energy is taken negative.

Answer:

The electron gain enthalpy values of halogens become more negative in the order F>Cl>Br>I. ... However the electron gain enthalpy of F is less negative than of Cl because of its small size. The additional electron in case of F will be added to the 2p orbital while in case of Cl it will go in the 3p orbital.
