In other words, within this benh, when Be bonds to H, it creates a hybridized orbital, which then bonds to the one S of the H. And let's see exactly that in this energy diagram. So we can imagine this being the energy diagram. So the higher up we go, the more energy we have. The lower we go, the less energy we have. What happens is the following. The Beryllium creates this hybridized orbital SD hybridized which comes from one S and one P an St hybridized orbital.
