Write the stability configuration of 
and predict their bond order, stability and magnetic character.
a) 
ion: It is formed from 
a molecule by the loss of one electron. This electron will be lost from 2p7 orbital of nitrogen molecule.
(i) Electronic configuration:
(iii) Stability: As the bond order is positive, it is quite stable.
(iv) Magnetic character: Since 2pz orbital has one unpaired electron, therefore it is paramagnetic.
(b) 
ion : It is formed by the gain of one electron by N2 molecule.
This electron will go to either 
orbital of N2 each of which is empty.
(i) Electronic configuration.
(ii) Bond order: Here Nb = 8; Na = 3
(iii) Stability. Bond order being positive, N2 is quite stable.
(iv) Magnetic character Due to the presence of an unpaired electron in 
*2px orbital, it is paramagnetic.
(c) 
ion: It is formed when molecule gains two electrons,
(i) Electronic configuration
(ii) Bond order: Here Nb = 8; Na = 4
(iii) Stability. Since bond order is positive, it is quite stable.
(iv) Magnetic character: As it has two unpaired electrons one each in 
orbitals, it is paramagnetic.
