Question
Explain the following, give an appropriate reason.
Ionisation potential of N is greater than that of O

Solution
N (Z = 7) 1s2 2s2 2px1 12py1 2pz1. It has exactly a half-filled electronic configuration and it is more stable. Due to stability, ionization energy of nitrogen is high.
O (Z = 8) 1s2 2s2 2px1 2py1 2pz1. It has incomplete electronic configuration and it requires less ionization energy.
I.E1N > I.E1O
