Question

what is electronic enthalphy????????​

Answer 1

Answer:

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.

Answer 2

Answer:

Electron gain enthalpy is defined as the amount of energy released when an electron is added to an isolated gaseous atom. During the addition of an electron, energy can either be released or absorbed. Hence, electron gain enthalpy for metals will be positive.
