WebA single orbital can hold a maximum of two electrons, which must have opposing spins; otherwise they would have the same four quantum numbers, which is forbidden. One electron is spin up (m s = +1/2) and the other would spin down (m s = -1/2). This tells us that each subshell has double the electrons per orbital. birch tree communities benton
