For example, the electron affinity of chlorine is −348.6 kJ/mol. The negative sign indicates that it is an exothermic change. Argon, however, has a positive electron affinity, indicating that formation of an argon anion requires energy to be supplied. milford quality landscaping

"WebElectron 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. " - Examples of electron affinity
