- For a hydrogen atom of a given energy, the number of allowed states depends on its orbital angular momentum. We can count these states for each value of the principal quantum number, \(n = 1,2,3\). However, the total energy depends on the principal quantum number only, which means that we can use Equation \ref{8.3} and the number of states counted.

Mar 02, 2020 · Energy level diagrams indicate us the different series of lines observed in a spectrum of the hydrogen atom. The horizontal lines of the diagram indicate different energy levels. The vertical lines indicate the transition of an electron from a higher energy level to a lower energy level. It is very important that as indicated in the diagram ... The true ground state of the hydrogen atom, n = 1, has zero angular momentum: since n = k + l + 1, n = 1 means both l = 0 and k = 0. The ground state wave function is therefore spherically symmetric, and the function w (ρ) = w 0 is just a constant.
