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.
