elektronaffinitet - Wiktionary

Electron Affinity in Periodic Table. Electron affinity (EA) or electron gain enthalpy or simply affinity in the periodic table define as the amount of energy released or liberated when an electron is added to an isolated neutral gaseous atom at its lowest energy level (ground state) to produce a uni-negative ion or anion. Chemical bonding - Chemical bonding - Electron affinity: Third in importance for bond formation after size and ionization energy is the energy change accompanying the attachment of electrons to a neutral atom.
