Deeper atomic orbitals would provide a large number of additional molecular orbitals, however the expected energies of these molecular orbitals would be much larger than the maximum observed energy of 5 eV (250 nm).
The attractive magnetic force in the anti-parallel spin electrons accounts for the anti-parallel pairing of electrons in atomic orbitals where the electrons are close together, this leading to the Periodic Table of elements.
Far from the surface and in the absence of a field, the atomic orbitals of A and B hybridize into molecular orbitals which we take to be a low-lying bonding orbital and an empty antibonding orbital.
