Greater shielding effect lithium sodium

WebHence, despite there being more positive charge, the amount of that charge that gets felt by the valence electron decreases because the distance between them has increased. It turns out, this increased distance which lowers Zeff outweights the increased Zeff from additional positive charge from the nucelus. Hence, Zeff decreases down a group. WebJan 8, 2024 · From sodium, it is two steps to aluminium but from potassium to gallium is 12 steps — the entire 3d block is wedged in-between. Thus, from a hypothetical starting point, we experience a much greater contraction by the time we reach gallium compared to aluminium. Note that it is irrelevant that the 3d electrons are there and ‘shielding’.

Shielding effect - Wikipedia

WebAn element's second ionization energy is the energy required to remove the outermost, or least bound, electron from a 1+ ion of the element. Because positive charge binds electrons more strongly, the second ionization energy of an element is always higher than the first. Created by Jay.
