Amongst the elements with the following electronic configurations which one of them may have the highest ionization energy?
A.[Ne]3s23p3✓ Correct
B.[Ne]3s23p2
C.[Ar]3d104s24p3
D.[Ne]3s23p1
Explanation
In general trend, ionization energy decreases down the group due to an increase in atomic radius and increases from left to right in periods due to a decrease in atomic size. Here, nitrogen (z=15) 2 3 Ne 3s 3p has the highest ionization energy as per the general trend and half-filled stability of p-orbitals.
