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。
-
And if we were to think about which one of these is better, it turns out that it's the same i in terms of formal charges, so that doesn't help us out.
而如果我们要考虑它们中的哪个更好，结果从形式电荷来看,它们之间没有区别，因此这不能帮我们进行判断。
-
In the first place, notice that sometimes story can be the dominant in obviously formal terms.
有时候故事明显,会占支配地位。
-
And it does, so we know that we're probably on target in terms of calculating our formal charge.
而它确实是这样，因此我们知道我们很有可能,算对了我们的形式电荷。
-
But I want you to tell me in terms of thinking about formal charge, which Lewis structure would you predict to be the most stable?
但我想让大家告诉我,从形式电荷的角度考虑，你会预测哪一个路易斯结构是最稳定的？
-
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。
-
It's always a good first approximation, because you need to start somewhere in terms of drawing Lewis structures, but then if you go and figure out the formal charge and you just have lots of charge separation or very high charges, like a plus 2 and a minus 2 and a minus 1 all different places in the atom, what it should tell you is maybe there's a better structure.
它总是一个好的第一近似，因为在画路易斯结构的时候,你总需要一个起点，但是如果你在算出形式电荷之后,发现有很多电荷分开了,或者说有很高的电荷，比如有一个正二，一个负二，还有一个负一1,在原子的各个地方，这应该就是在告诉你,或许还有一个更好的路易斯结构。
-
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。
