The value of the angular quantum number, l gives an information about the energy subshell and the number of orbitals. Hence, the subshell notation for the quantum number in question is d and has 5 orbitals
The angular quantum number, l = 2
The energy subshell corresponding to l = 2 would be ;
- s ___ p ___ d ____ f
- 0 ___ 1 ___ 2 ____ 3
Hence, the quantum number corresponds to the d - subshell
According to the magnetic quantum number, m ;;
At, l = 2 :
m = {-2, - 1, 0, 1, 2} = 5
The value of m denotes the number of orbitals which is 5
Therefore, the subshell notation and number of orbitals are d and 5 respectively.
