Difference Between Electronegativity and Electron Affinity

WebThe electron affinity, E ea, is the change in energy when an electron is added to an isolated atom in the gaseous phase. We have seen that ionization energies are always positive, but electron affinities are generally negative for many atoms, because energy is released when an electron is added. The more negative the electron affinity, the ... WebSuch calculations can be made using quantum chemistry methods. Electronic affinity is a property specific to a given element. However, it may be slightly different for individual isotopes.
