The table shows the radii, in pm, for several ions. $[1\,\text{pm} = 10^{-12}\,\text{m}]$ Caesium chloride, $\text{CsCl}$, has a lattice arrangement that is unlike both sodium chloride, $\text{NaCl}$, and magnesium oxide, $\text{MgO}$. Which factor seems to decide the lattice type of these three compounds?
- Athe charge on the cation
- Bthe ratio of the ionic charges
- Cthe ratio of the ionic radii
- Dthe sum of the ionic charges
