You will know if you need to solve for the bond order when there are more than two atoms that you can find in the molecule.

These are the steps that you have to do so that you can look for the bond order:

• Draw the Lewis structure first because this will make things easier.
• Count the total number of bonds available.
• You should now count the number of bond groups between the different atoms.
• Divide the number of the bonds that you can find between the different atoms that are available.
• The more bond groups that are available, the better.

With all of these things in mind, determining the bond order is something that you can do every time you need to do so.

You need to know if there are more than two atoms that can be found in the molecule.

If you answer yes, these are the steps that you have to do to know the bond order:

• Create the Lewis Structure.
• Count the number of bonds that are available based on the Lewis Structure you have created.
• You need to count the number of bond groups between the different atoms that are available.
• Divide the number of bonds with the number of bond groups between the different atoms.

It will also help if you know the formula for calculating the bond order, which is bond order = [Number of electrons in bonding molecules] minus [number of electrons in the antibonding molecules.]

Bond energy is an attraction that can be measured between various atoms in a molecule. To find the bond energy, follow these steps

• First, write out the bond energy equation

• Then, draw the chemical equation, which show show all the bonds that the molecules have.

• On the left side, identify any broken bonds

• On the right side, count all of the bonds

• Then, identify all the bond energies and multiply that number by the amount of bonds that have been broken.

• Add all the broken bond energies together

• Then, add all the formed energy bonds together

• Subtract the amount of the formed bonds from those that were broken to get the bond energy.
