MCQ
The two electrons occupying the same orbital are distinguished by:
- Aprincipal quantum number
- Bazimuthal quantum number
- Cmagnetic quantum number
- ✓spin quantum numbers
✓
Answer
Correct option: D.
spin quantum numbers
d
Two electrons occupying the same orbital are distinguished by spin quantum number $(s)$.
Two electrons occupying the same orbital are distinguished by spin quantum number $(s)$.
Out of these, one electron will have $s =+\frac{1}{2}$ and other electron will have $s =-\frac{1}{2}$.
These two electrons have the same values of principal quantum number $(n)$, azimuthal quantum number $(l)$ and magnetic quantum number $( m )$ respectively.
