Without the half filled orbital,the overlapping is not possible ,therefore Be2 molecule does not exist. This problem has been solved! Step 2: Draw the molecular orbital diagram. A bond order greater than zero means that more electrons occupy bonding MOs (stable) than antibonding MOs(unstable). However, the van der Waals force exists between helium atoms as shown by the existence of liquid helium, and at a certain range of distances between atoms the attraction exceeds the repulsion. Calculation of bond order. Previous work is scrutinized with an eye to the instability problems inherent in various Hartree-Fock schemes. Likewise, is a bond order of 0 stable? This pairs up with the electron in the highest occupied σ-orbital. Answer. The ground states of the above molecules are examined mainly through multi reference configuration interaction methods using an aug-cc-pVQZ basis set. Divide the result by 2 to get the result. The bond number itself is the number of electron pairs (bonds) between a pair of atoms. To calculate bond order in chemistry, subtract the number of the electrons in the antibonding molecules from the number of electrons in the bonding molecules. From the above MO diagram we can see that number of elctrons in the bonding and antibonding orbital is same and hence Be does not form Be2 molecule(for. σ12e σ22e π11e σ30e π20e σ4e bond order ½σ bonding e σ antibonding e so if we take the bonding effect σ2 2e as not quite 1 π11e as 05 then the bond order of be2 … Electronic Structure .
