The molecular orbital diagram for: Be Be. But it seems to me that since the next electron would go into the π u orbital, which is a bonding orbital, Be 2-would have a bond order of 0.5, and Be 2 2-would have a bond order of 1, since it would have 4 in bonding (2 in σ and 2 in π)and only 2 in the σ*. 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 is estimated to be 05 bo 10 ie bound. As discussed in class the MO diagram for B 2 shows that it has two unpaired electrons (which makes it paramagnetic) and these electrons are in bonding molecular orbitals resulting in the equivalent bond strength of one bond. I understand that Be 2 cannot exist, since it has as many electrons in the antibonding as in the bonding orbitals..
