So we started with 10 valence electrons, we used up 8 of those electrons in terms of making bonds.

我们一开始有十个价电子，然后用掉了八个电子来成键。

So let's see, we started with 8 bonding electrons, and we used up only 4, so the answer is yes, we have 4 bonding electrons left.

那么让我们来看看，我们一开始有八个成键电子，然后只用掉了四个，因此答案应该是还有剩余，我们还剩下了四个成键电子。

so you can see that there is going to be two sets in antibonding, three sets in bonding for a net of one, giving us the single bond.

因此你能看到,反键轨道上有两组，三组成键，得到一组净成键，所以成的是单键。
