How to Calculate the Energy Degeneracy of a Hydrogen Atom

WebJun 25, 2024 · 8. In QM, energy levels of atoms are quantized. This means that rather than the system being able to have any energy, there are instead only discrete energy levels the system can be observed to be in. The "lowest energy state" is just the state with the smallest amount of energy. WebJan 30, 2024 · For one configuration, the level with the largest S, which has the largest spin degeneracy, has the lowest energy. If two levels have the same S value, then the one with the larger L (and also the larger orbital degeneracy) have the lower energy.
