HEYA!!
----------
➡ELECTRON GAIN ENTHALPY: IT is the energy released when an electron is a
Is added to a neural gaseous atom . It is represented by Heg.
Now , coming to the Question:
✨The Electron Gain Enthalpy of Halogen [ Cl , Br, I etc ] is highly negative . This is due to their electronic Configuration. Halogen needs only one more electron to complete their octet .
Thus, because of this they have a highly negative value of electron gain enthalpy....

HEY MATE HERE IS YOUR ANSWER
The electron gain enthalpy for halogens is high negative because they can acquire the nearest stable noble gas configuration by accepting an extra electron. Noble gases have large positive electron gain enthalpy. This is because the extra electron is placed in the next higher principal quantum energy levels.
halogens have maximum negative electron gain enthalpy in the respective periods of the periodic table? Answer: This is due to their small size and higher effective nuclear charge. Due to these two parameters halogens easily gain one electron to complete their octet and attain Noble gas configuration.
Halogens have the smallest size in their respective periods and therefore high effective nuclear charge. As a consequence, they readily accept one electron to acquire noble gas electronic configuration.
