So, in this case, we're just drawing the molecular orbital diagram for the valence electrons, so we have three for each.
所以在这个例子里面,我们只需要画出,价电子的分子轨道图,所以每个有3个电子。

This should make a lot of sense, because we know that a hydrogen has 1 s as it's outer-most or valenceorbital, so it can be filled up just with two 1 s electrons.
