And I am going to superscript it molecular orbital, and this upper one, to indicate that it's antibonding, has the asterisk.
我将给分子轨道加上标，这个上标，表示反键轨道，有一个星号。
-
It turns out that the antibonding orbital is a little bit higher from the atomic orbital level than the bonding orbital is lower.
这证明了,反键轨道,比原子轨道高,成键轨道比原子轨道第。
-
And because of the way those antibonding orbitals are stacked, the two electrons go one each into those antibonding.
因为这样,反键轨道被堆积了，这两个电子都填到各自的反键轨道。
-
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。
-
And this one here, because it is at a higher energy is called antibonding molecular orbital.
这里的这个，因为处在一个较高的能级,被叫做反键分子轨道能级。
-
And this one, just for completeness, is what the antibonding orbital would look like.
然而这个，只是为了其完全性，把反键轨道也表示出来。
-
You have two electrons in antibonding to kind of offset the bonding.
你有两个电子,在远离成键轨道的反键轨道上。
-
Here is the antibonding and here is the bonding.
这是反键轨道，这是成键轨道。
-
And then the antibonding which we don't care about.
然后他们的反键轨道我们不去管了。
-
These are the bonding and antibonding.
这是成键和反键。
-
s plus 1s gives you this oval ellipsoid which is the bonding, and here are the antibonding, and then these are the energy levels that I have been drawing for you.
s和1s上两个电子组成的键合电子成椭圆形,这是成键，这是反键电子，这些是刚刚已经画过的能级,我也给你们画了。
-
This is sigma star with the antibonding orbital that came from 1s, and it is a molecular orbital.
这是sigma星，来自于1s的反键轨道,它是一个分子轨道。
