In valence bond theory, the focus is on discussing the bonds, but it should look very familiar to you, because there's two types of bonds that we want to discuss here.

So what I want to tell you is we also always get the same bond order if we instead only deal with the valence electrons.
我想要说的是我们如果,只考虑价电子也可以得到相同的键序。
All right, so that's really all there is to thinking about valence bond theory in terms of the most simple explanation here.
好了,这就是,价电子轨道理论的,最简单的解释。
OK, then it says draw a single bond from each surrounding atom to the central atom, and subtract two valence electrons.
