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.

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。

And you can do this any time if you have Lewis structures that you're choosing between.

而每当你遇到需要从几个可能的,路易斯结构中选择的情况。

And so what we ended up doing is the last four weeks of class after we had grounded it in the history of the modern university, understood the structure of it, we had the students select topics that they were really interested in.

所以我们最后选择,在最后四周，在我们了解了,现代大学的历史，理解大学的结构之后，我们让学生们选择一些,他们真正感兴趣的话题。

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.

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。
