Options
- Ah/2
- Bh/
- Ch/2
- 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
