WebZeff = 7+-when Cl gains one electron to become Cl1-, its configuration becomes [Ne] 3s² 3p⁶.-although an electron has been added to the outer energy level, there is no change in nuclear charge and the extra electron increases the electron-electron repulsions, thus increasing the size of the Cl1- anion when compared with a neutral Cl atom. WebLet's look at some actual ionization energies for elements in group one. And so we can see here some elements in group one. And so for hydrogen, it would take 1,312 kilojoules per mole of energy to pull an electron away from hydrogen. For lithium, it would take about 520 kilojoules per mole to take an electron away.

WebSo, that is part of the issue. Unlike electronegativity, the electron affinity does not have a strong periodic value. The electron affinity measures the energy released when an electron is captured by the atom (or a molecule), forming an anion with a 1− charge. This is not necessarily directly related to the "willingness" for the element to ...
