What are the differences between Electron Affinity and Electron Gain Enthalpy?

Although there is little difference between the two, Electron Gain Enthalpy and Electron Affinity are sometimes referred to.

The amount of energy that an electron releases when it is added to a gaseous atom is called electron gain enthalpy. Energy can be either released or absorbed during the addition of an electron.

Sign the Electron Gain Enthalpy Convention

Negative: Energy is released and an electron is accepted.

Positive: Energy is added to an atom by adding an electron.

The word electron affinity is the love of an electron. It is the opposite of electron gain enthalpy.
