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 2px2y1z1
N(7) =1s2 2s2 2px1y1z1 exactly 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
