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。

Let's go ahead and draw our Lewis structure based on the rest of the rules now that we have a skeleton.

好，首先，我们看看它的路易斯结构。

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

那么，让我们很快地画出臭氧的路易斯结构。

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

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 we'll talk specifically about drawing Lewis structures and then about formal charge and resonance, which are within Lewis structures.

因此我们会专门讲一讲,如何来画路易斯结构,然后再讨论形式电荷与共振论，它们也属于路易斯结构的范畴。

So now that we have enough practice drawing Lewis structures let's talk about actually figuring out this formal charge.

那么现在我们已经做了足够多的画路易斯结构的练习,让我们来讨论一下如何得出形式电荷。
