But to speak of an intentional structure as a center is not at all the same thing as to speak of an intending person, author, being, or idea that brought it into existence, because that's extraneous.

但是讲到一个作为中心的意向性结构,与讲到一个创造它的人，作者，存在，或概念是完全不同的，因为那是外来的。

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。
