where ϕ(r) = Ae-r/aB is the ground-state solution of the radial Schrodinger equation for the Hydrogen atom (aB is Bohr's radius), and P(r) = 4πr2|ϕ(r)|2
is the probability density that the electron would be located in the spherical shell between r and r + dr. First normalize the wavefunction to obtain the constant A:

∫dr P(r) = 1
