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.
5p, 4d, 5d, 4f, 6s

उत्तर
| Orbitals | s | p | d | f |
| l | 0 | 1 | 2 | 3 |
| Orbitals | n | n + l |
| 5p | 5 | 6 |
| 4d | 4 | 6 |
| 5d | 5 | 7 |
| 4f | 4 | 7 |
| 6s | 6 | 6 |
Thus the increasing order of energy is 4d < 5p < 6s < 4f < 5d.
