State of hydrogen atom (n) = 1(due to ground state). Radius of hydrogen atom (r) = 0.53 Å. Atomic number of Li (Z) = 3. Radius of Li2+ ion = r x n²/Z = 0.53 x 1²/3 = 0.17

The radius of hydrogen atom in ground state =[(nhx2eπ)^2]/mz
If we put value of all these terms that is, n=1,h=6.026*10^-27 ,e=4.8*10^-10
m=9.1*10^-28, z=1
Radius=0.53 amstrong
Radius of hydrogen atom is directly proportional to principle quantum no.
The first bohr orbit has degeneracy one. These orbits are called stationary orbit. It can be shown by the calculation that the radius of hydrogen atom in the ground state is 0.53 Amstrong.
