Bohr Model: Orbits, Speed & Angular Momentum

The magnetic moment of electron due to orbital motion is proportional to

(nn = principal quantum number)

Show answer and solution

Answer: (a)

  1. Orbital magnetic moment μ=eL2m\mu = \frac{eL}{2m}, and L=nh2πL = \frac{nh}{2\pi}.
  2. μ=neh4πm∝n\mu = \frac{neh}{4\pi m} \propto n
  3. So the answer is (a) nn.
