Why Ionisation potential of Fluorine is more than Nitrogen?
Despite the fact that nitrogen has half filled orbital and it makes it more stable
Answers
Answer:
the size of flourine is much more smaller than nitrogen when an electron is removed the size becomes even smaller. so, it is difficult to remove second electron from F than N . hence, F has higher second ionization potential than N.
ccording the Hund's rule, half filled and full filled orbitals are more stable. this is because of half filled electronic configuration of nitrogen which is more stable than that of partially filled configuration of oxygen.

Explanation:
The correct reason for this is not that nitrogen's electron becomes more stable whie jumping from one orbital to another and losing energy but it is that it's not Nitrogen whose ionization energy becomes higher but it's the other way ....
i.e. it's Oxygen whose ionization energy becomes much lower than expected value because the inner three electron are arranged symmetrically and the shielding effect thus provided us quite high.
So , as shielding effect increases z-effectuve decreases and so ionization energy of Oxygen decreases...
U may check this my analyzing the real values in the form if graph :
So, this graph clearly shows that the ionization energy if Nitrogen is increasing according to it's original trend but it's oxygen's ionization energy which shows a dip ...
Trust me , thus us the right explanation.

I even argued with one of my teachers about it and at last they had to accept it
