... no quantum numbers other than energy, and so the only quantum number that can separate two electrons is the spin. One electron can have spin up and the other spin down. So we can have at most two electrons. In the other shells we can have more electrons because the state has other quantum numbers su ...

... Spin angular momentum in quantum mechanics does not arise from a particle actually spinning like a top, rather it is an intrinsic property of a particle, like its mass. An important thing to note is that spin is quantised. It can only have discrete values. For example, protons, neutrons and electron ...
