If a ques is asked that find value of quantum numbers of electron in 2s orbital so for the electrons in 2s orbitals will azimuthal quantum number be 1 or 0...because here n=2
Dear Student,
The principal quantum number describes the size of the orbital whereas the azimuthal quantum number describes the shape of the orbital.
Now, l = n - 1 , where l = azimuthal quantum number and n = principal quantum number
By convention, the following letters are used to describe the shape of the orbital, irrespective of primary quantum number:
So, all s - orbitals will have l = 0, whether it is 1s , 2s or 3s.
Thus, the azimuthal quantum number for 2s orbital will be 0. For 2p orbital, it will be 1.
Hope it helps.
Regards

By convention, the following letters are used to describe the shape of the orbital, irrespective of primary quantum number:
- s orbital, l = 0
- p orbital, l = 1
- d orbital, l = 2
- f orbital, l = 3
So, all s - orbitals will have l = 0, whether it is 1s , 2s or 3s.
Thus, the azimuthal quantum number for 2s orbital will be 0. For 2p orbital, it will be 1.
Hope it helps.
