Explanation:
Electron gain enthalpy is the amount of energy released when an electron is added in the shell of an atom.
The element in whose shell the electron gets easily added has more negative electron gain enthalpy.
Both fluorine and chlorine belong to group 17 of halogens (7 electrons in valence shell) and have highly negative electron gain enthalpies as they can easily gain one electron to gain a stable electronic configuration (8 electrons in valence shell)
According to periodic properties, as we move down in a group of the periodic table the electron gain enthalply.
