Question

Define electron gain enthalpy ​

Answer 1

Electron gain enthalpy is the energy required to add an electron in a neutral atom. Because, in most of the cases atom releases energy, the electron gain enthalpies are negative. As we move from left to right in the periodic table the electron gain enthalpy (its negative value), in the same period, increases.
