उत्तर
- Each main shell contains a maximum of 2n2 electrons.
For ‘M’ shell, n = 3.
Therefore, the maximum numbers of electrons present in the ‘M’ shell = 2 × (3)2 = 18. - The distribution of these electrons in shells, subshells, and orbitals can be given as follows:
Value of n Values of l Values of ml Values of ms 3 0 0 `±1/2` 1 −1 `±1/2` 0 `±1/2` +1 `±1/2` 2 −2 `±1/2` −1 `±1/2` 0 `±1/2` +1 `±1/2` +2 `±1/2`

The arrangement of orbitals on the basis of energy is based upon their (n + l) value. Lower the value of (n + l), lower is the energy. For orbitals having same values of (n + l), the orbital with lower value of n will have lower energy.
Based upon the above information, arrange the following orbitals in the increasing order of energy.
1s, 2s, 3s, 2p
