Consider two different hydrogen atoms. The electron in each atom is in first excited state. According to Bohr's model, electrons will have: |
different energies but the same orbital angular momentum same energies and the same orbital angular momentum same energies but different orbital angular momentum different energies and no orbital angular momentum |
same energies and the same orbital angular momentum |
The correct answer is Option (2) → same energies and the same orbital angular momentum According to Bohr's model of hydrogen atom - (A) Energy of the electron in the first excited state (n = 2) depends upon only on the Quantum number n, and since both the the hydrogen atom have electron in the same excited state (n = 2), the energy of the electrons will be same. (B) The orbital angular momentum of an electron - $L=nh$ for $n=2$, the orbital angular momentum for both atoms will be, as $L=2h$. |
