Place the following in order of increasing IE1 N F As
A) As < N < F
B) As < F< N
C) N D) F N< As
E) F < AS < N

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
