WebElectron affinity means love for electron. It is the negative of the electron gain enthalpy. By using the concepts of thermodynamics, we find a relationship between electron gain enthalpy and electron affinity i.e. E l e c t r o n g a i n e n t h a l p y = e l e c t r o n a f n i t y − 5 2 R T. where, R= universal gas constant. WebElectron affinity is the energy change that results from adding an electron to a gaseous atom. For example, when a fluorine atom in the gaseous state gains an electron to form F⁻(g), the associated energy change is -328 kJ/mol.Because this value is negative (energy is released), we say that the electron affinity of fluorine is favorable.
