我们看到键序是0，同样的，键非常非常的弱。

So what we see is a bond order of 0, and again, the bond is very, very weak.

两个，OK，很好，同样的，我们会看到键序是0。

PROFESSOR: Two. OK, good. So again, we're going to see that we have a bonding order of 0.

我想要说的是我们如果，只考虑价电子也可以得到相同的键序。

So what I want to tell you is we also always get the same bond order if we instead only deal with the valence electrons.

So let's figure out the bond order for our two molecules here that we figured out the electron configuration for.

让我们看看这里,两个分子的键序是多少。

/2 So the bond order is going to be equal to 1/2, and then it will be 2 minus 2.

它的键序等于，然后乘以2减去2。

And you can go ahead and tell me what you think the bond order is going to be for this molecule.

你们告诉我你觉得,这个分子的键序应该是怎样的。
