43: Bohr's Model and Physics of the Atom
- #1The minimum orbital angular momentum of the electron in a hydrogen atom is
(a) h
(b) h/2
(c) h/2Ï€
(d) h/λdigAnsr: cAns : (c) h/2π
According to Bohr's atomic theory, the orbital angular momentum of an electron is an integral multiplt of h/2Ï€.
∴ `` {L}_{\,\mathrm{\,n\,}}=\frac{nh}{2\pi }``
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=\frac{h}{2\pi }``
