Lithium is the smallest ion in group $1$. It would therefore be expected to have the highest ionic mobility and hence solutions of its salts would be expected to have a higher conductivity than solutions of caesium salts. Explain why this is not true.

The atomic radius for lithium is $1.23 \mathrm{\AA }$. When the outermost $2\mathrm{s}$ electron is ionized off, the ionic radius of ${\mathrm{Li}}^{+}$ is $0.76 \mathrm{\AA }$. Assuming that the difference in radii relates to the space occupied by the $2\mathrm{s}$ electron, calculate what percentage of the volume of the lithium atom is occupied by the single valence electron. Is this assumption fair? (Volume of a sphere is $\frac{4}{3}{\mathrm{\pi r}}^3$)
