text: It is especially notable that the energy of the hydrogen atom is determined solely by the principal quantum number of the orbital occupied by the electron (except for some small effects that are not of concern here); that is, in hydrogen, the electron configurations of the third shell, for example, are equi-energic (of the same energy, whichever one the electron occupies), which is not the case with any of the other atoms, all of which contain two or more electrons.
