So we can write out what the electron configuration is here, and I think that I have already written that out for you in your notes.
我们可以在这里写出电子构型，我觉得我已经在你们,讲义上写出来了。
-
And we can also write this in an even simpler form, which is what's called electron configuration, and this is just a shorthand notation for these electron wave functions.
而且我们也可以将它，写为一个更简单的形式，它叫做电子构型,这个仅仅是这些电子波函数的。
-
So if we think about what we would do to actually write out this configuration, we just write the energy levels that we see here or the orbital approximations.
如果我们考虑我们所做的去,实际写出电子构型，我们只是写出我们看到的能级,或者是轨道近似就可以了。
-
So let's do this considering, for example, what it would look like if we were to write out the electron configuration for oxygen where z is going to be equal to 8.
我们来做这个考虑，举例来说,如果我们写出,有效电荷量为8的氧的电子构型。
-
And the reason that we use it is that it is incredibly accurate, and allows us to very, very quickly predict and to predict accurately, in most cases, what the electron configuration of molecules are going to be.
我们用它是因为它极为精确，并且能让我们非常非常快地预测,而且是准确地预测，大多数情况下，分子应该具有的电子排布。
-
But, of course, what you saw in recitation, and hopefully, what you can now think very quickly by looking at this, is that this is not the only configuration of pi bonds that we could have in benzene.
当然，你们在习题课看到过，你们通过看这个可以很快的想到，这不是苯环里,唯一的π键构型。
-
And this is the same periodic table that you're going to get in your exams, so it's good to practice doing your problem-sets with that periodic table so you're not relying on having the double check right there of seeing what the electron configuration is.
这也是你们考试时会用到的相同的表,这样你们就不会，所以使用周期表来做问题集,是很好的练习,这样你们就,不会依赖于再次确认,电子构型是什么了。
-
So, if we want to think about what the first ionization energy is of boron, what you want to do is write out the electron configuration, because then you can think about where it is that the electron's coming out of.
如果我们要考虑,硼的第一电离能，你首先要做的是写出它的电子排布，因为在这之后,你才能知道拿走的是哪里的电子。
-
And again, I've written for you, but you can figure out what the electron configuration is just by writing up in this order here.
同样，我已经写出来了，但你们可以把这个写出来,就知道电子轨道构型是什么。
-
If we look at this configuration, what we say is all of the electrons in these inner shells are what we call core electrons.
如果我们看到这个构型，我们所说的是,所有的内层,都是核电子。
-
So, as an example, let's take argon, I've written up the electron configuration here, and let's think about what some of the similarities might be between wave functions in argon and wave functions for hydrogen.
所以作为一个例子我们来看看氩，我已经把它的电子构型写在这里，我们来考虑氩和,氢波函数之间的,一些相似性。
-
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。
-
But that's an idea of what it actually means to talk about electron configuration.
但那是一个实际了解什么是,电子构型的思路。
-
So basically, at the time he was just going on size and then traits, but what we actually know today is that we can also order things in the periodic table by electron configuration.
基本上，在当时他只能通过大小,和特性来进行，但是现在我们已经知道了,我们还可以通过电子排布来对它们进行排序。
-
So let's think about what the valence electron configuration is here.
让我们看看这里的,电子构型是什么样的。
-
So, Lewis structures are really a model for a way to think about what the valence electron configuration is, and as I said, it's not based on quantum mechanics, it's something that Lewis observed far, far before quantum mechanics were discovered.
路易斯结构实际上是一个用来考虑价,电子排布的模型，而就像我说的，它并不以量子力学为基础，而是路易斯在以前发现的,在量子力学出现很早前。
-
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。
-
N 2 So any chemist should be able to just look at n 2 and know that it's a triple bond, but that's not something that we've learned how did to do yet, so let's go ahead and start a new topic that's going to allow us to have some sort of sense of what the valence electron configuration, which includes whether something's a single or double or a triple bond can be figured out for any given molecule.
任何一个化学家都应该能够仅仅通过看到2,就知道它有一个三键,但是我们还没学习如何做到这点，因此下面我们就开始进入一个新的主题,它将使我们能够有一定的认识,对于价电子的排布情况，包括可以对任何一个给定分子中的键是单键双键,还是三键作出判断。
-
So let's think about what this valence electron configuration is for c 2.
让我们来看一下C2的,价电子构型是怎么样的。
