प्रश्न
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.
5f, 6d, 7s, 7p

उत्तर
| Orbitals | s | p | d | f |
| l | 0 | 1 | 2 | 3 |
| Orbitals | n | n + l |
| 5f | 5 | 8 |
| 6d | 6 | 8 |
| 7s | 7 | 7 |
| 7p | 7 | 8 |
Thus the increasing order of energy is 7s < 5f < 6d < 7p.
