Solution
Molecular orbital diagram of nitrogen molecule (N2)
Electronic configuration of N atom 1s2 2s2 2p3
Electronic configuration of N2 molecule:
σ1s2, σ1s*2, σ2s2, σ2s*2, π2py2, π2pz2 σ2px2
Bond order = `("N"_"b" - "N"_"a")/2`
`= (10 - 4)/2` = 3
Molecule has no unpaired electrons hence it is diamagnetic.
