The bond order of the nitrogen molecule N2 can be determined using molecular orbital theory. Nitrogen has 7 electrons, so a nitrogen molecule N2 has a total of 14 electrons. These electrons fill the molecular orbitals in the following order: 1s, *1s, 2s, *2s, 2px, 2py, and 2pz.Here is the electron configuration for N2:- 1s: 2 electrons- *1s: 2 electrons- 2s: 2 electrons- *2s: 2 electrons- 2px: 2 electrons- 2py: 2 electrons- 2pz: 2 electronsTo calculate the bond order, we use the formula:Bond order = number of electrons in bonding orbitals - number of electrons in antibonding orbitals / 2For N2:Bond order = 10 - 4 / 2 = 6 / 2 = 3Therefore, the bond order of the nitrogen molecule N2 based on molecular orbital theory is 3.
