So again you can see as we're filling up our molecular orbitals, we're using the exact same principle we used to fill up atomic orbitals.

当我们填充轨道的时候可以看到，我们用的是和,填充原子轨道一样的原则。

Because step five is that we need to fill in our bonding electrons, and we start it with filling in two electrons per bond.

因为第五步要做的是将我们的成键电子填在这，所以我们开始在每个键处填上两个电子。

So carbon has four valence electrons, so if we talk about c 2, again we're going to start filling in our molecular orbitals, and now we're going to have eight electrons to fill into our molecular orbitals.

碳有4个价电子，所以如果我们考虑C2的话，同样，我们开始填分子轨道，现在我们有8个电子,要填入分子轨道。
