Its going to equal to ½ times the number of electrons in the bonding molecular orbital minus the number of electrons in the antibonding molecular orbital. Hence the bond order of Li2 is 1 2 1 2 1 2 1 2 1 2 1 indicating a single sigma bond because they are in the σ2s MO a sigma orbital. Best Chemistry Youtube Channel 2021 Digitalkemistry Chemistry Youtube Supportive And the two electrons of the 2s orbitals will occupy the bonding MO leaving the antibonding MO empty. .
