So, this one can be tricky because oxygen looks like it's in the middle because of the way it's written, but we need to start by looking at the lowest ionization energy.
这个例子可能有些狡猾,因为氧看起来是在中间的,因为它是这样写的,但是我们需要从寻找最低的电离能开始。
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。
