# The Minimum Orbital Angular Momentum of the Electron in a Hydrogen Atom is - Physics

MCQ

The minimum orbital angular momentum of the electron in a hydrogen atom is

• h

• h/2

• h/2π

• h

#### Solution

h/2π

According to Bohr's atomic theory, the orbital angular momentum of an electron is an integral multiplt of h/2π.
∴ L_u = (nh)/(2pi)

Here,
n = Principal quantum number

The minimum value of n is 1.
Thus, the minimum value of the orbital angular momentum of the electron in a hydrogen atom is given by
L = h/(2pi)
