Answer :
Answer:
A) As < N < F
Explanation:
Ionization energy refers to the minimum amount of energy required to remove an electron from a gaseous atom r in.
The genera trend of IE, is that it increases across the period from left to right and decrease down the group in a periodic table.
As belongs to period 4, this means it as the lowest ionization energy.
Nitrogen and Florine belong to the same period however Florine has a higher ionization energy.
In order of increasing IE;
As < N < F
