In hydrogen atom, which energy level order is not correct?
1s<2p<3p
2p=2s<3s=3p
2p>2s>1s
2p<3s=3d

A: Electronic energy for hydrogen atom of different orbitals follow the sequence 1s lt 2s = 2p lt 3s = 3p = 3d R : Electronic energy for hydrogen atom depends only on n and is independent of 'l' & 'm' values .

Arrange the following in order of increasing energy for hydrogen atom 1s 2s 2p 3s 3p 3d 4s 4p
