प्रश्न
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 same orbital angular momentum according to the Bohr model? Justify your answer.
उत्तर
No, Because according to Bohr's model, En = `13.6/"n"^2` and electrons having different energies belong to different levels having different values of n.
So, their angular momenta will be different, as
`"L" = "mvr" = ("nh")/(2pi)`
