Oct 29, 2015 · 25. Electron affinity and electronegativity are related. Electron affinity is a meas-ure of the ease with which an atom gains electrons. Electronegativity is a measure of the ability of an atom to attract electrons. Therefore, atoms with a high negative electron affinity are also the most electronegative. 26. The physical and chemical properties Nov 26, 2018 · The electron configuration can be seen as consisting of the core electrons, which is equal to the configuration of the most recent noble gas, plus the valence (outer electron) configuration of the element. So the electron configuration of calcium (Ca) which has 20 electrons, can be written as: [Ar]4s². That gives you the correct electron configuration, argon 4s 2, 3d 1. But it's implying that the d orbitals, the 3d orbitals fill after the 4s orbital and is therefore a higher energy and that's not true actually. It does help you to just assume that's the case if you're writing an electron configuration but that's not what's happening in reality. This 1 electron will fill one-half of the 4s orbital. Therefore, the electron configuration of Potassium is 1s^2 2s^2 2p^6 3s^2 3p^6 4s^1.
