NEET Chemistry Quantum Mechanical Model MCQ Question with Solution

What is the correct sequence of orbital energy levels for the hydrogen atom?

A

1s < 2s = 2p < 3s = 3p = 3d

B

1s < 2s < 2p < 3s < 3p < 3d

C

1s = 2s < 2p = 3s < 3p < 3d

D

1s < 2p < 2s < 3p < 3s < 3d

Option A

In a hydrogen atom, the energy of orbitals increases as 1s < 2s = 2p < 3s = 3p = 3d, where orbitals with the same energy are degenerate.
