actually our third, but the second one we're going to talk about in terms of formal charge, which is thionyl chloride.

实际上是第三个，但它是第二个,形式电荷的例子，也就是亚硫酰氯。

So, if we think about the second case here where we have c n minus, now we're talking about a molecule with a net charge of negative 1.

那么，如果我们考虑的是第二个例子,也就是氰离子，那么现在我们讨论的是一个净电荷量为负一的分子。

We'll get to oxidation number in the second half of this course, but it's not in any way the same idea as formal charge.

我们会在课程的后半部分讲到氧化数，但它和形式电荷完全不是同一个概念。

We said that that second electron was so far out of the picture, that it had absolutely no affect on what the charge was felt by that first electron.

我们说第二个电子远离这张图片,这样它就彻底的对,第一个电子感觉到的电荷没有影响了,所以。

Often a good thing to start with is to put the lowest ionization energy atom in the middle, and if you don't have charge separation then go with that structure, but if you do find you have a lot of separation, such as the case in negative 2, positive 2, and minus 1, then you want to say wait a second, this is really bad in terms of formal charge, let me go ahead and see what other options I have here.

通常一开始把电离能最低的原子,放在中心位置就很好了，如果你发现电荷没有分开,那么这个结构就没问题了，但是如果你发现有很多分开的电荷，比如这种情况，有负二，正二和负一，那么你会想要说等一下，从形式电荷来看这很不好，让我去看看其它可能的选择。
