Energy of the Electron & Energy Levels

Angular momentum of an electron in a hydrogen atom is 3hπ\frac{3h}{\pi}, then the energy of the electron is _____ eV.

Show answer and solution

Answer: (c)

  1. L=nh2πL = \frac{nh}{2\pi}; given L=3hπ=6h2πL = \frac{3h}{\pi} = \frac{6h}{2\pi}, so n=6n = 6.
  2. E6=−13.636=−0.38E_6 = \frac{-13.6}{36} = -0.38 eV
  3. So the answer is (c) −0.38-0.38 eV.
