The similarities are both orbitals are in a spherical shape and differences between the both belong to different energy levels the hydrogen atom is 2s orbital and 3s orbital.
The s-orbitals are the spherical-shaped orbitals where the probability of finding the electrons are always more than they can contain only two electrons.
S-orbitals can have different energy levels as the level increase if there is an increase in the number of electrons all the s-orbitals have the same shape and size.
therefore, the hydrogen atom 2s orbital and 3s orbital similarities are both orbitals are in a spherical shape, and the differences between both belong to different energy levels.
