那么，这些就是在我们需要在,不同的路易斯结构之间做选择的时候,我们如何用形式电荷来进行判断的各种方法。

So, these are the different ways that we can actually go ahead and use formal charge when we're choosing between different types of Lewis structures.

我们还可能遇到另外一种情况，那就是在我们需要进行，选择的两种路易斯结构中，形式电荷具有相似的绝对值。

So, we can also get into a case where we have similar values in terms of absolute values of formal charge between two different molecules we're deciding between in their Lewis structures.

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。

And the last thing we do for any of our structures to check them and figure out are these valid or not valid, are these good Lewis structures is to check the formal charge.

而为了检验任何一个结构是否有效,看它们是不是好的路易斯结构,我们要做的最后一件事就是检查形式电荷。

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。
