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。
-
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。
-
Then something that you probably have a lot of experience with is talking about electron configuration and writing out the electron configuration.
然后有一些事情是,你们可能有较多经验,那就是讨论电子构型以及,写出它们。

These are all isoelectronic, they all have the same electron configuration. And we can also think about going back to atomic size for a second.
这些都是等电子的，它们都有相同的电子排布，而,我们还可以再回想一下原子尺寸的概念。
-
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.

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。
-
So for example, if we think about fluorine, 1 s 2 2 s 2 2 p 5 that has an electron configuration of 1 s 2, 2 s 2, 2 p 5, so all we would need to do is add one more electron to get the same configuration as for neon.
比如，如果我们考虑氟原子的话，它的电子排布是，因此我们所需要做的就是给它加上一个电子,使得它与氖原子的电子排布相同。
-
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, in this one we're selecting the correct electronic configuration for an ion.
那么，这次我们要做的是,选出一个离子正确的电子排布。
-
So here we're talking about v plus 1, so if we were to write it just for the neutral electron itself, we would find that the electron configuration is argon, that's the filled shell in front of it.
这里我们要分析的是正一价的钒离子，因此，我们先写出中性原子的电子排布，可以发现，其原子实是氩原子的电子排布，这些壳层已经被占满了。

God's extremely peculiar configuration of the human body You read this and you realize that Samson is really on to something here Why didn't, we ask with Samson God implant the sense of sight in human beings just as he implanted the sense of touch or feeling?
还有上帝对人体极其古怪的构造,读这些你们就能意识到参孙在这确实知道一些意图,我们和参孙一样也想问,为什么上帝不让人类拥有视觉,就像让人类当初拥有触觉一样？
-
So, selenium 2 minus is what's going to be isoelectronic, because if you add two electrons to selenium, you'll get the same electron configuration that you have for krypton here.
负二价的硒离子将是等电子的，因为如果你给硒原子加上两个电子，你会得到,和氪原子相同的电子排布。

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。
-
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.
