Halogens have very high electron gain enthalpy. Give reason.
Answers
Answer:
The halogens have a strong tendency to accept electrons due to their small size and effective nuclear charge so they have maximum negative electron gain enthalpy in their respective periods of the periodic table.

EXPLANATION OF DOM WORDS IN THE ANSWER
ELECTRON GAIN ENTHALPY - Electron gain enthalpy is defined as the amount of energy released when an electron is added to an isolated gaseous atom.
ISOLATED NUETRAL GASEOUS ATOM - When an atom is free from other atoms in gaseous state, it is called isolated gaseous atom. No energy is required to separate it further from other atoms.
