EASYMCQ SINGLEIChO (Chemistry Olympiad)Physical ChemistryAtomic StructureIntro [Manipal 2010] Which one of the following statements in relation to the hydrogen atom is correct?
0.3s, 3p and 3d-orbitals all have the same energy
1.3s and 3p-orbitals are of lower energy than 3d-orbital
2.3p-orbital is lower in energy than 3d-orbital
3.3s-orbital is lower in energy than 3p-orbital
Explanation
In a hydrogen atom (one-electron system), energy depends only on n. All orbitals with the same n (3s, 3p, 3d) are degenerate (same energy).
