The bond order of a nitrogen molecule N2 can be determined by examining its molecular orbital configuration. Nitrogen has 7 electrons, so a nitrogen molecule N2 has a total of 14 electrons. The molecular orbital configuration for N2 is:1, 1*, 2, 2*, 2^4To calculate the bond order, we use the formula:Bond order = number of electrons in bonding orbitals - number of electrons in antibonding orbitals / 2For N2, the bonding orbitals are 1, 2, and 2^4, which have a total of 10 electrons. The antibonding orbitals are 1* and 2*, which have a total of 4 electrons.Bond order = 10 - 4 / 2 = 6 / 2 = 3The bond order of a nitrogen molecule N2 is 3, which means it has a triple bond between the two nitrogen atoms.
