There are some exceptions, which we'll get to later, but the only a big exception here is with hydrogen, which has a special stability that's associated with two electrons.

但也有一些例外我们将以后再讲，但这里只有一个较大的例外，氢，它的稳定性比较特殊，只需要两个电子。

But what I'm going to tell you already is this is a case where, in fact, it's an exception to the idea that the lowest energy structure has the lowest ionization energy in the middle, and we can figure this out when we look at formal charge.

但是我已经告诉大家这个例子，实际上，是中心原子电离能最低的结构,的能量最低这一思路的一个例外，我们可以通过形式电荷看出这一点。

With one exception, I won't be spending very much time talking about the readings.

但是有一个例外，我不会花很多时间讨论阅读材料的内容。

Remember that when we're talking about 4s1, 3d10, that's one of those exceptions where a completely filled d orbital is more stable than we would expect.

回想上节课的内容我们知道,当我们讨论4s1，3d10，的时候，这是其中一个例外的情况,当，d，轨道全满的时候,电子排布要比我们想象的更加稳定。
