And it is well known that (i) ANIONS are larger than their parent atoms given that they physically expand the electronic shell of the particle, and that (ii) cations are smaller than parents in that we remove a valence electron that PREVIOUSLY defined the radius of the atom. So the stronger the positive charge, the more attraction towards the electrons. Explain your reasoning. 3, 1 Atomic size decreases left to right on the periodic table because the attractive force of the protons on the same number of rings of electrons increases for each element as we move left to right. Although it is true that $\ce{Kr}$ and $\ce{Sr^2+}$ have the same electron orbital configuration and $\ce{Sr^2+}$ has two more protons than $\ce{Kr}$, $\ce{Sr^2+}$'s greater nuclear attraction is likely countered by the nature of metal ions being more willingly to lose electrons, which implies the electrons are more loosely held by the nucleus than the noble gas $\ce{Kr}$.
