See explanation below.
Work Step by Step
For a given level (n), the sublevels in H have the same energy, whereas in many-electron, species, the sublevels are staggered in energy. The staggering is due to the higher likelihood of core penetration (slightly less shielding by core electrons) for s compared to p orbitals. For H or any one-electron species (like Be3+), there is no shielding, so all the sublevels have the same pattern as in H.
