For an electron in a hydrogen atom, the minimum orbital angular momentum is given by

Options

  1. Ah/2
  2. Bh/
  3. Ch/2
  4. Dh

Correct answer

C. h/2

Step-by-step solution

According to Bohr's atomic model, the orbital angular momentum of an electron in a hydrogen atom is quantized and is given by L = nh 2 where n = 1, 2, 3, For the minimum orbital angular momentum, the principal quantum number n must be minimum, i.e., n = 1 . L_ min = h 2
