Lewis structure

Well , first of all , let 's look at the Lewis structure .

好，首先，我们看看它的路易斯结构。

The first step in any Lewis structure 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。

So , let 's quickly go through the Lewis structure for ozone .

那么，让我们很快地画出臭氧的路易斯结构。

So this is our Lewis structure here .

这就是Lewis结构。

This is a good way to actually check if your Lewis structure 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。

So , this is our Lewis structure 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。

And this structure that I 've depicted here using the X 's and O 's is called the Lewis structure .

我在这儿描述的结构，用X和O表示电子的方式叫做Lewis电子式。

All right . So , let 's go ahead and draw our Lewis structure 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。

So , what will start with on Monday is doing the most simple example of methane using these Lewis structure 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。

So what we should have is8 valence electrons in our Lewis structure .

所以Lewis结构里，有8个价电子。

So , which atom would you expect to be in the center of a Lewis structure for thionyl chloride ?

那么，大家认为那个原子应该在，亚硫酰氯的路易斯结构的中心位置呢？

So , let 's go ahead and draw our Lewis structure 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。

But I want you to tell me in terms of thinking about formal charge , which Lewis structure 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？

So , that 's his gift to us : the Lewis structure , 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。

All right , so this is the same procedure that we 're going to go through , regardless of what kind of Lewis structure 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。

So , our second step , as we go through our Lewis structure 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。

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 Lewis structure .

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。

Step three in our Lewis structure 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。

And in terms of thinking about it for organic chemistry or if you 're interested in thinking about the mechanism maybe by which it is toxic , a first step would be to draw its Lewis structure .

而为了在有机化学中思考它，或者如果你对它，有毒的机理感兴趣的话，第一步要做的应该就是画出它的路易斯结构。

In terms of picking a Lewis structure that 's going to be the lowest energy , what you want to do is put the atom with the lowest ionization energy in the center of your atom .

为了挑选一个具有，最低能量的路易斯结构，你需要把电离能最低的原子，放在最当中的位置。

So if we went through and drew out our Lewis structure 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 .

那么如果我们按照流程，经过所有的步骤来画路易斯结构，我们会得到这样的路易斯结构，然后我们可以算出所有的形式电荷。

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 Lewis structure before you can answer this question .

如果你还没有点答案，或者你想改变你的答案，记住你也许需要在回答问题前写点东西，比如画一画Lewis结构，来得到最终。

So it looks a lot less messy if we just draw our Lewis structure 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 .

这看起来整洁了不少，如果我们把氰化氢的路易斯结构画成这样的话，这样我们就有氢与碳之间的单键和碳与氮之间三键，然后还有一对孤对电子在氮这里。

Lewis Raise your hand if you didn 't have time to figure out the Lewis structure .

没时间画出，结构的同学请举手。
