Question

We know that ionization energy increases along period .                                                                                                                                                                                                                How this trend of ionization energy is correct  O < N < F 

Read 2 Solution.

it is due to their difference in electronegativity.

F(9) = 1s2 2s22px2 y2z1

 

O(8)  =1s2 2s2 2px2y1z

 

N(7) =1s2  2s2 2px1y1zexactly half filled & thus more stable which lead to higher I.E 

  , along period IE increases due to increase in nuclear charge while no. of orbits remain same 

REMEMBER THE ELECTRONEGATIVITY ORDER IS F>O>N BUT THERE IS NO RELATION IT HAVE WITH IE
