"We all agree, " Lincoln continued, "that the so-called seceded states are out of their correct relation with the Union.

All right. We've got a big majority, and both are logical ways of thinking, but it turns out that the majority is correct, which is not always the case, but the electron is not ejected in this case.

好，大多数人都这么认为，这两种看法都是合乎逻辑的，但结果是大多数人是对的，这种情况不经常发生，但是电子在这种情况下,确实不会被逐出。

His idea was, the formula written for the opposite one will have the opposite angle; That turns out to be the correct answer.

他的方法是,反过来的方程,以相反的角来表示,那就能推出正确的答案了

Well, for our purposes, both are correct and we'll know how to figure this out on tests.

这个,对课堂而言,两种都正确,我们会在测试中明白原因的

We will find out later that is almost correct.

我们之后会发现这是几乎正确的。

So, it turns out that the majority of you got the correct answer, which is that it's aluminum.

从结果看大多数人,都做对了，答案应该是铝。

And I know there's a lot to talk about this competition, but let's just get into listening mode here and talk about how we can figure out what the correct electron configuration is for this ion.

我知道刚才关于这次比赛大家有很多话要聊，但是请大家先转换到听讲的模式,来看看如何才能弄清楚,这个离子正确的电子排布。

Now, the naive guess may be 45, but it turns out the naive guess is actually correct.

现在,简单的猜测是 45°,但事实上这样的猜测是正确的

So it looks like not too many more than half of you got this correct, so make sure you can look at your periodic table and figure out how to think about ionization energy in terms of z effective, not just in terms of memorizing what that trend is.

看起来只有一半多一点的人,做对了，所以请大家务必做到能够通过观察周期表,并在考虑电离能时,从有效核电量的观点出发，而不是仅仅依靠记住这个规律。

So, for example, if we think of the fluorine minus case, would you expect fluorine minus to be larger or smaller than neutral fluorine? Okay. I heard mostly larger, but a little bit of a mix in there, and it turns out that larger is correct.

比如，如果我们来考虑一下负一价的氟离子的话，大家认为它大一些还是小一些？,对比于比中性氟原子，好的，我听到大部分人说大一些，但是也有一些不同意见，而正确答案应该是大一些。

We don't always want to go and solve the Schrodinger equation, and in fact, once we start talking about molecules, I can imagine none of you, as much as you love math or physics, want to be trying to solve this Schrodinger equation in that case either. So, what Lewis structures allow us to do is over 90% of the time be correct in terms of figuring out what the electron configuration is.

我们并不想每次都去解薛定谔方程，而且实际上，一旦我们开始讨论分子，我可以想象,你们中没有一个人，不管你有多么热爱数学或物理，会想去解这种情况下的薛定谔方程,总之，路易斯结构能让我们,有超过，90%，的概率判断出正确的,电子排布。

And seeing that it's a 4 p has two nodes - let's just write this out since not everyone did get it correct.

因为有些同学没答对,我们还是写一下,如果我们讨论的是4p轨道。
