Azimuthal quantum number

               Azimuthal quantum number is describes the shape of the orbitals. It is denoted by 'l', is the quantum number associated with the angular momentum of an atomic electron. ( It describes the subshell energy level ). Orbitals have shapes that are best described as spherical ( l=0 ), the polar ( l=1) and cloverleaf (l=2). The values of l ranges from 0 to n-1.
                           l = 0,1,2,3,......n-1
l=0 is called s orbital.
l=1 is called p orbital.
l=2 is called d orbital.
l=3 is called f orbital.
If n=1, l=0 ( 1 sub level ) s orbital.
   n=2, l=0 and 1 ( 2 sub level ) p orbital.
   n=3, l=0,1 and 2 ( 3 sub level ) d orbital.
   n=4, l=0,1,2 and 3 ( 4 sub level ) f orbital.
The energy of the subshell increases with       ( s á  p á  d á  f ).
Azimuthal quantum number otherwise known as subsidiary or angular quantum number or orbital quantum number.
