All right, so that's s p 3 hybridization, but those aren't the only type of hybrid orbitals that we can form. Let's take a look at what happens if instead of combining all four orbitals, we just combine three of those orbitals, and what we'll end up with is s p 2 hybridization.

好了，这是sp3杂化，但这并不是我们可以,形成的唯一类型的杂化轨道,让我们来看看，不是四个轨道结合，我们仅仅结合3个轨道。
