利用简单的价电子成键理论，我们预计，要把所有甲烷中没有配对的电子，和氢原子中没有配对的电子配对来形成键。

So, using our simple valence bond theory, what we would expect is that we want to pair up any unpaired electrons in methane with unpaired electrons from hydrogen and form bonds.

本质上就是由于，未配对电子配对导致的成键。

Essentially what you have is bonds resulting from the pairing of unpaired electrons.

因为我们有一对，在2s轨道里已经配对了，所以只剩下两个电子可以用来成键。

Because we have paired set in a 2 s orbital, so all we're left essentially is two electrons that are available for bonding.

So, if we hybridize just these three orbitals, what we're going to end up with is our s p 2 hybrid orbitals.

我们会看到现在有3个未配对的电子，可以成键。
