Question

How do sub-shells looks like ? Explain with Diagram. (Azimuthal quantum number)

Answer 1

                                  S orbital
                                 -------------

S orbital hav spherical symmetrical shape. 
 i.e the probability of finding electron is same in all direction at a particular distance from the nucleus. S orbital hav ( n - 1 ) nodes. 
[ For your information ---> 1s orbital don't have nodes ]
I hav attached their picture in the attachment. ( both 1s & 2s )
                        
                                      P orbital
                                    --------------
p orbital hav Dum.b- bell shape
       There are 3 p orbitals, they are Px, Py, Pz..Surface boundary diagram is shown in the attachment.
 
                                      d orbital
                                    --------------
 
d orbital hav double dum.b- bell shape. there are 5d orbitals. they are
dxy , dyz , dxz , dx²-y² , dz² .. Figure is shown in attachment. 
           
                                   f Orbital
                                 --------------

One looks like a dum.b bell with two rings. The others have six lobes each in different directions. All have a node at the nucleus. F orbital hav diffused shape.

      Azimuthal quantum number / Subsidiary quantum number ( ℓ )
    ---------------------------------------------------------------------------------

For S orbital , ℓ = 0

For p orbital , ℓ = 1

For d orbital , ℓ = 2

For f orbital, ℓ = 3
