And this spin is an intrinsic quality of the electron, it's a property that is intrinsic in all particles, just like we would say mass is intrinsic or charge is intrinsic.

So what that means is that we're limited in any atom to having two electrons per orbital, right, because for any orbital we can either have a spin up electron, a spin down electron, or both.
這意味著在一個原子內,每個軌道上可以有兩個電子，對吧，因爲對任何軌道,我們可以有自鏇曏上或者自選曏下或者兩者都有。
