Greater shielding effect lithium sodium

WebShielding is when the inner electrons partially block the attractive force between the positively charged nucleus and the outer electron (s). This makes it easier to remove the outer electron (s) from the atom.

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’.

Because positive charge binds electrons more strongly, the second ionization energy of an element is always higher than the first. Created by Jay.

WebA higher effective nuclear charge causes greater attractions to the electrons, pulling the electron cloud closer to the nucleus which results in a smaller atomic radius. Down a group, the number of energy levels (n) increases, so there is a greater distance between the nucleus and the outermost orbital. This results in a larger atomic radius. 2.
