Moving a stack of size 3, again, if I want to go over there, I need to make sure I can put the spare one over here before I move the bottom one, I can't cover up any of the smaller ones with the larger one, but I can get it there.

移动上面的三个圆盘的话，我在移动最底下的圆盘之前，同样要确保剩下的,是在另外一个柱子上，因为我不能把大的圆盘,放在小的上面。

All right, so I did this not at all purposely, but this can point out for you that you need to make sure that the number of electrons that you have in your molecular orbital does match up with the total number that you have in your atomic orbitals.

我并不是故意这么做的，但这告诉我们必须要保证,分子轨道里的电子数,和原子轨道里的,总电子数能对上。

我还想提一点关于检查,你的路易斯结构的建议，不管它们是什么，你总是应该回去检查一下,我有十个，然后数一数，二，四，六，八，十个，因为你总是需要确保实际价电子的数量,与你在结构中算出的数量相等。
