Solution:
This can be done by the molecular orbital theory.
First, write the molecular orbital electronic configuration of N2 molecule.
The total number of electrons present in the dinitrogen molecules is =14 .
All the 14 electrons distributed in the bonding and antibonding molecular orbitals given below. N2→KK0σ2s2σ⋆2s2π2px2=π2py2σ2pz2 N2+→KKσ2s2σ⋆2s2π2px2=π2py22pz1
As per the molecular orbital electronic configuration, we can understand that the last electron is removing from the σ2pz bonding molecular orbital.
