Answer
The number of chemical bonds between two atoms is called the bond order.
The value of the bond order can be calculated with the formula:
$B =\frac{1}{2}\times (N_{bonding}-N_{antibonding}) $
i.e., half the difference between number of bonding and antibonding orbitals of the molecule.
Work Step by Step
For example, Nitrogen, $N_{2}$, has a bond order of 3 since it has a $\textbf{triple bond}$ between two atoms $(N≡N)$
