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 $\ce{Kr}$. e. 2, 3, In the Lewis structure for SF4, S has ___(i)_____ lone pairs of electrons and 2 Pb2+(aq) + 2 I-(aq) PbI2(s) in an ionic compound? a.
