The orbital having two radial as well as two angular nodes is:
  1. (A)4 d
  2. (B)5 d✓ Correct
  3. (C)4 f
  4. (D)

Answer: (B)

Solution

For an orbital with principal quantum number and azimuthal quantum number , the number of angular nodes is and the number of radial nodes is .
Two angular nodes fix , so the orbital is of the type.
Two radial nodes then require

The orbital having two radial and two angular nodes is .
