MCQ
The two electrons occupying the same orbital are distinguished by:
  • A
    principal quantum number
  • B
    azimuthal quantum number
  • C
    magnetic 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 $(s)$.

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.
