Answer: Inside a multielectron atom, the electrons present inside the internal shells defend the electrons within the valence shell within the attraction from the nucleus or they work as a monitor in between the nucleus and these electrons.
Gain of an electron causes the formation of the anion. The size of an anion will probably be much larger than that in the parent atom since the addition of one or more electrons would lead to enhanced repulsion among electrons and reduce in efficient nuclear cost.
Atomic dimension. With the increase in atomic measurement, the number of electron shells boosts and thus the power of attraction involving the electrons as well as the nucleus decreases. Hence the ionization enthalpy decreases.
