The innermost orbital radius of the hydrogen atom for n=1 is defined by the equation below.

rn = h2 n2

4 π2Kmq2

Note that all factors in the equation are constants with the exception of n2. The value of r1 is 5.310-11 m, or 0.053 nm. Use this information to calculate the radii of the second, third, and fourth allowable energy levels in the hydrogen atom.
