Two electrons occupying the same orbital are distinguished by :
Principle quantum number
Magnetic quantum number
Azimutual quantum number
Spin qauntum number
Spin Quantum Number (s) -
It has two values +1/2 and -1/2
-
For the two electrons occupying the same orbital value of n, l amd m are same but is different i.e.
Option 1)
Principle quantum number
This is incorrect option
Option 2)
Magnetic quantum number
This is incorrect option
Option 3)
Azimutual quantum number
This is incorrect option
Option 4)
Spin qauntum number
This is correct option
