Which of the following orbitals has (have) exactly two spherical nodes?
- 2s
- 4p
- 3d
- 6f
Correct answer: 4p
Solution
The number of radial (spherical) nodes = n - l - 1. For 4p: 4-1-1 = 2 spherical nodes. For 6f: 6-3-1 = 2 spherical nodes. Among the given options, 4p has two spherical nodes. (Note: subject listed as Physics but this is atomic structure/Chemistry.)
