MCQ
The angular momentum of an electron depends on
- APrincipal quantum number
- ✓Azimuthal quantum number
- CMagnetic quantum number
- DAll of these
✓
Answer
Correct option: B.
Azimuthal quantum number
b
The angular momentum of an electron depends on azimuthal quantum number $(l)$
The angular momentum of an electron depends on azimuthal quantum number $(l)$
Orbital angular momentum is calculated by the expression $\mu_1=\sqrt{l(l+l)} \frac{ h }{2 \pi}$
