What is angular momentum of an electron in fourth orbit of hydrogen atom?

Options

  1. Ah 2
  2. Bh
  3. C2 ~h
  4. D3 ~h

Correct answer

C. 2 ~h

Step-by-step solution

The angular momentum of an electron in a given stationary orbit of hydrogen atom = mvr = nh 2 (where n =1,2,3 ) Angular momentum of an electron in fourth orbit of hydrogen atom = 4 h 2 = 2 h
