Bond order, as introduced by Linus Pauling, is defined as the difference between the number of bonds and anti-bonds.. I have learned that single bonds are weakest but are the longest whereas for example, a double bond is stronger than a single bond … According to the molecular orbital theory, in a supposed He2 molecule, both the if we draw its MOT DIAGRAM, 2 e's enter the … Bond order = 1/2 (#e- in bonding MO - #e- in antibonding MO) For H 2, bond order = 1/2 (2-0) = 1, which means H 2 has only one bond. What is the bond order of He2? The bond number itself is the number of electron pairs (bonds) between a pair of atoms. a. This overlap forms a molecular bond between the two atoms with its own molecular orbital shape.
