how to share information onlineWebElectron affinity refers to the ability of elements to release energy, thus showing the ease and spontaneity, of adding an extra electron to the sole atom. Another difference is that electronegativity is a value from 0 to 4.0, while electron affinity is a defined thermodynamic constant for each element in kJ per mole. notion default property valueWebElectron 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.
