1. Let's go ahead and draw our Lewisstructure based on the rest of the rules now that we have a skeleton.
既然我们已经有了框架，那我们就根据剩下的规则，继续画路易斯结构。

2. So this is our Lewisstructure here.
这就是Lewis结构。

3. Well, first of all, let's look at the Lewisstructure.
好，首先，我们看看它的路易斯结构。

4. So, let's quickly go through the Lewisstructure for ozone.
那么，让我们很快地画出臭氧的路易斯结构。

5. So what we should have is 8 valence electrons in our Lewisstructure.
所以lewis结构里，有8个价电子。

6. the first step in any Lewisstructure is drawing the skeletal structure.
画任何路易斯结构第一步,都是先画出它的骨架。

7. So, this is our Lewisstructure here, hopefully you can see why it's not linear.
这就是Lewis结构，希望你们能看出来为什么它不是直线型的。

8. This is a good way to actually check if your Lewisstructure is correct or not.
这是检验你的路易斯结构，是否正确 的一个好方法。

9. All right. So, let's go ahead and draw our Lewisstructure here with sulfur in the middle.
好，那么，让我们来把我们的，路易斯结构画在这，硫在中间。

10. And, he didn't publish anything related to the Lewisstructure until about 1912 or 1913.
直到1912或，他都没有出版任，何与路易斯结构式有关的东西。

11. So, let's go ahead and draw our Lewisstructure based on the rest of the rules now that we have a skeleton.
那么，让我们继续画我们的路易斯结构，看看在得到骨架之后还有哪些规则。

12. So, that's his gift to us: the Lewisstructure, and the idea that you could share electrons and form a covalent bond.
这就Lewis给我们的礼物，Lewis结构，你能够通过公用电子，形成共价键。

13. So, what will start with on Monday is doing the most simple example of methane using these Lewisstructure rules.
因此，下周一上课，我们会先以最简单的例子--甲烷开始，使用这些路易斯结构的规则。
来自互联网
14. All right. So let's think about how to draw the oh, actually, let me let you tell me how we should start this Lewisstructure.
好，那么我们来想一想应该怎么画，噢，实际上，我想让大家来告诉我，我们应该怎么开始画这个路易斯结构。

15. But I want you to tell me in terms of thinking about formal charge, which Lewisstructure would you predict to be the most stable?
但我想让大家告诉我，从形式电荷的角度考虑，你会预测哪一个路易斯结构是最稳定的？
来自互联网
16. All right, so this is the same procedure that we're going to go through, regardless of what kind of Lewisstructure we're going to draw.
好的，这就是我们画路易斯结构，所需要完成的步骤，不管什么样的路易斯结构都要这样做。

17. So, at the end of the class on Friday, we saw that list of eight steps that you always need to go through when you draw a Lewisstructure.
在上周五的课的最后，我们看到了一张,包括八个步骤的流程表。

18. So, our second step, as we go through our Lewisstructure rules, is to figure out how many valence electrons we have in our entire molecule.
那么，我们的第二步，按照路易斯结构的规则，应该是判断在整个分子中，包含多少个价电子。
来自互联网
19. If it were linear, which 32% of you seem have thought, that would have meant that our Lewisstructure had no lone pairs in it, right, and that's not the case.
如果是直线，就像32%的同学认为的那样，这意味着Lewis结构里没有孤对，对吧，这是不可能的。
来自互联网
20. So, if we use those two tips to try to figure out a structure, a skeletal structure, we would get this structure here if we write out the full Lewisstructure.
21. Step three in our Lewisstructure rules is to figure out how many electrons we would need in order for every single atom in our molecule to have a full valence shell.
路易斯结构规则的第三步是，找出让分子中每个原子的价壳层，都排满应该需要多少个价电子。
来自互联网
22. So in terms of remaining valence electrons we have 12, so we can finish off each of our Lewisstructures, so that's our first structure there, and our second structure there.
23. So it looks a lot less messy if we just draw our Lewisstructure like this for h c n, where we have h bonded to c triple bonded to n, and then a lone pair on the nitrogen there.
24. So if you haven't clicked in yet, or if you want to change your answer, keep in mind that you might need to jot down, - for example, a Lewisstructure before you can answer this question.
25. So if we went through and drew out our Lewisstructure following each of our steps, what we would get is this as our Lewis structure here, and we could figure out all of the formal charges.
26. So if we went through and drew out our Lewisstructure following each of our steps, what we would get is this as our Lewis structure here, and we could figure out all of the formal charges.
