# Consider two different hydrogen atoms. The electron in each atom is in an excited state. Is it possible for the electrons to have different energies but the same orbital angular momentum according to the Bohr model?

Answer :

From the angular momentum and energy formula of nth electron, we have,

,

Where n is nth orbit

h is Planck’s constant,

m is mass of electron

in permittivity in vacuum

and and is the angular momentum and energy of the electron in nth orbit

Clearly from above formula for orbital angular momentum and energy of orbital of electron, each n^{th} orbit will have unique orbital angular momentum and energies. ∴ it is not possible for electron to have different energy but same orbital angular momentum.

PREVIOUSWould the Bohr formula for the H-atom remain unchanged if proton had a charge (+4/3) e and electron a charge (−3/4) e, where e = 1.6 × 10–19C. Give reasons for your answer.NEXTPositronium is just like a H-atom with the proton replaced by the positively charged anti-particle of the electron (called the positron which is as massive as the electron). What would be the ground state energy of positronium?
