This larger shell reduces electron-electron repulsions so the entering electron does not experience much repulsion. The chlorine atom has the same electron configuration in the valence shell, but because the entering electron is going into the n = 3 shell, it occupies a considerably larger region of space and the electron–electron repulsions are reduced. Click here to buy a book, photographic periodic table poster, card deck, or 3D print based on the images you see here! In contrast, the second electron affinity is always positive because the increased electron–electron repulsions in a dianion are far greater than the attraction of the nucleus for the extra electrons. This is because the incoming electron is added to an already negative ion Electron affinity is a measure of the energy released when an extra electron is added to an atom. Whether you’re a student, professional, or just. Electron affinity increases going left to right across a period because of increased nuclear attraction. Moving from left to right and bottom to top on the period table, electron affinity increases.
