h
h/2
h/2π
h/λ
Advertisements
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)`
