The formula to calculate the radius of Lithium-ion is given by

$R_{Li}=R_H\times \frac{n^2}{Z}...(1)$

Substitute the values of the known parameters into equation (1) to calculate the required radius of the ion.

$$\begin{array}{rl}{R}_{Li}& =\frac{0.51\times 25}{3}\times 10^{-10}m\\ & =425\times 10^{-12}m\end{array}$$
