Let's draw the Molecular orbital diagram of Helium gas (He 2 ) and find out the bond order. Number of Bonding electron = 2 Number of antibonding electrons = 2 Bond order = (Nb - Na) / 2 = (2- 2)/ 2 = 0 From the above Molecular orbital diagram of Helium gas, it can be concluded, there are two bonding and anti-bonding electrons in Helium gas.

Bond order 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. The antibonding orbital is empty. Thus, H 2 is a stable molecule. Again, in the MO, there is no unpaired electron, so H 2 is diamagnetic. References Chang, Raymond. Physical Chemistry for the Biosciences.

Each hydrogen atom contributes one electron, and thus, H− 2 has three electrons while H+ 2 has one. Each hydrogen atom contributes one 1s atomic orbital, and thus, the orbitals overlap according to MO theory to form one σ1s and one σ* 1s MO by conservation of orbitals. If you calculate their bond order, you get: BOH+ 2 = 1 2(Bonding − Antibonding)

Bond Order. The bond order for a molecule can be determined as follows: bond order = ½ (bonding electrons − antibonding electrons). Therefore, the H 2 molecule has a bond order of ½ (2 − 0) = 1. In other words, there is a single bond connecting the two H atoms in the H 2 molecule. In the case of He 2, on the other hand, the bond order is ...

2) Stability of molecules in terms of bond order. Bond order is defined as half of the difference between the number of electrons present in the bonding and antibonding orbitals. Bond Order = ½ ( N b - Na) The molecule is stable if N b > Na ie. bond order is positive. The molecule is unstable if N b < Na i.e. the bond order is negative or zero.

Bond order is the number of possible bonds between two atoms. As the bond order of diatomic nitrogen is 3 i.e. two nitrogen atoms are connected with a triple bond (N≡N). The bond order signifies the strength of the bonding between atoms. The bond is stronger when the bond order is high and vice versa. The bond order also tells about the ...

What is the bond order of H2? Formula for bond order is: BO = 1/2 {no. of electron in bonding orbital - no. of electron in antibonding orbital} Since H2 has 2 electron {1 from both H} and both electron will be in 1s2 (bonding orbital) So, BO = 1/2 {2-0} =1 4.5K views View upvotes Related Answer Abhishek Singh , Carbon

A further example is given using the NH3 MO diagram. Here, they calculate the bond order as 3, ignoring the fact that the NH3 a1 orbital is weakly bonding. If we were to in theory calculate the MO diagram for NH3 in a trigonal planar geometry (same as for BH3), we would also get the bond order as 3.

The bond order tells us the average number of bonds between the bonded atoms. In a diatomic molecule such as `O_2`, the bond order simply tells the number of bonds between the two atoms. The bond order can be interpreted from MO diagrams using the following formula: `"Bond Order" = 1/2 [("Bonding "e^-)-("Antibonding " e^-)]`
