Question

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, solve the questions given below:

Which of the following orbitals has the lowest energy?

5p, 5d, 5f, 6s, 6p

Solution

Orbitals n n + l
5p 5 6
5d 5 7
5f 5 8
6s 6 6
6p 6 7

The highest energy orbital is 5f
