For an atom or ion having single electron, compare the energies of the following orbitals.

\mathrm{S}_1=

A spherically symmetrical orbital having two spherical nodes.

\mathrm{S}_2=

An orbital which is double dumb-bell and has no radial node.

\mathrm{S}_3=

An orbital with orbital angular momentum zero and three radial nodes.

\mathrm{S}_4=

An orbital having one planar and one radial node.

View answer and explanation

Correct option: B

\mathrm{S}_1=\mathrm{S}_2=\mathrm{S}_4 < \mathrm{S}_3

Option A is correct because for a single-electron system, energy depends only on the principal quantum number (n), so orbitals with the same n have the same energy.
