OK, now, this is a more formal look at that structure.

对，这是一个更规范的结构。

All right. So formal charge can actually help us out when we're trying to decide between several Lewis structures that look like they might be comparable in terms of which might be the lower energy or the more stable structure.

好的，形式电荷真的可以,帮助我们决定,在几种路易斯结构中,哪个更可能符合能量更低,或者结构更稳定的要求。

But what I'm going to tell you already is this is a case where, in fact, it's an exception to the idea that the lowest energy structure has the lowest ionization energy in the middle, and we can figure this out when we look at formal charge.

但是我已经告诉大家这个例子，实际上，是中心原子电离能最低的结构,的能量最低这一思路的一个例外，我们可以通过形式电荷看出这一点。
