The examples we've done so far have been pretty straightforward, so we haven't needed to use formal charge to make this kind of decision.
我们之前做过的例题,都是非常简单直接的,因此我们还不需要,用形式电荷来做这种决定。
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。
What we need to do is get rid of the Coulomb tag that we have - that's how we measure our electron charges - charge, and so we use this epsilon nought quite often, this permativity constant of a vacuum to make that conversion.
怎么量度电子电荷,所以我们会经常用到,这个epsilon,nought记号,这是真空中的介电常数,我们还要指出,这个介电常数。
