That makes sense because we know that every single electron has to have its own distinct set of four quantum numbers, the only way that we can do that is to have a maximum of two spins in any single orbital or two electrons per orbital.

那个讲得通,因为我们知道每一个电子,都有它自己独特的量子数,我们能做的唯一方式是,在任一单个轨道中最多有两个自旋电子,或者每个轨道有两个电子。
