So far, we have tried to combine the one s atomic orbitals of two identical H atoms. So they're both neutral. That means they have one electron and one proton each. And so far we saw that when we combine these two atomic orbitals of the one of the H atom one that's orbitals, we form something called a five bonding molecular orbital. Or simply a bonding molecular orbital. And we said that the energy of this molecular orbital, of the Bonding molecular orbital, is lower than either of the atomic orbitals from which we're forming.
