Let's re-draw this, so it looks a little bit neater, where we have a triple bond in the middle instead, and again, we need our negative 1 charge there.

让我们重写这个，这样看起来更整洁一点，我们有一个三键在中间，同样地，我们这里需要一个负电荷。

So again, this is an anti-bonding orbital, and what you see is that there is now less electron density between the two nuclei than there was when you had non-bonding.

同样的，这是反键轨道，你们看到当你有反键轨道的时候,两个原子核中间的电子密度更小了。

So, somewhere in between, the bonds are, we have a range of bonds between ionic on the one hand, and perfectly covalent on the other hand.

因此在中间，这些键，一方面是离子性，另一方面是完美的共价键。

There's absolutely nothing that tells us which atoms we should put it between, because they're both oxygen-oxygen.

我们没有任何理由把它们,放在其中一对原子中间，因为它们都是氧氧键。
