How do not the energy of orbits in an atom vary?

The energies of orbitals of hydrogen atom are in the order

Calculate the radius of the third Bohr orbit of hydrogen atom and the energy of electron in that orbit.

How much energy is required to ionise an H atom if the electron occupies n=5 orbit? Compare your answer with the ionisation enthaply of H atom (anargy required to remove the electronic from n=1 orbit).

The energies of orbitals of H- atom are in the order

How do potential energy and K.E. of a spring vary with displacement ? Is this variation different from variation in potential energy and K.E. of a body in free fall ?
