The bond order of the nitrogen molecule N2 can be determined by looking at its molecular orbital diagram or using the formula:Bond order = number of electrons in bonding orbitals - number of electrons in antibonding orbitals / 2For N2, there are 10 valence electrons 5 from each nitrogen atom . In the molecular orbital diagram, these electrons fill the following orbitals:- 1 2 electrons - 1* 2 electrons - 2 2 electrons - 2 4 electrons So, there are 8 electrons in bonding orbitals 1, 2, and 2 and 2 electrons in antibonding orbitals 1* . Using the formula:Bond order = 8 - 2 / 2 = 6 / 2 = 3The bond order of the nitrogen molecule N2 is 3.
