Hence, much energy is required to remove an electron from the outermost orbit. So, the element with [Ne] 3 s2 3 p3 configuration has highest ionisation energy.

Q. In the following, the element with the highest ionisation energy is

$[N e] 3 s^{2} 3 p^{1}$

$[N e] 3 s^{2} 3 p^{3}$

$[N e] 3 s^{2} 3 p^{2}$

$[N e] 3 s^{2} 3 p^{4}$

Elements having half-filled or fully filled orbitals are more stable. Hence, much energy is required to remove an electron from the outermost orbit.
So, the element with [Ne] $3 s^{2} 3 p^{3}$ configuration has highest ionisation energy.

Q. In the following, the element with the highest ionisation energy is

[Ne]3s23p1

[Ne]3s23p3

[Ne]3s23p2

[Ne]3s23p4

Elements having half-filled or fully filled orbitals are more stable. Hence, much energy is required to remove an electron from the outermost orbit. So, the element with [Ne] 3s23p3 configuration has highest ionisation energy.

$[N e] 3 s^{2} 3 p^{1}$

$[N e] 3 s^{2} 3 p^{3}$

$[N e] 3 s^{2} 3 p^{2}$

$[N e] 3 s^{2} 3 p^{4}$

Elements having half-filled or fully filled orbitals are more stable. Hence, much energy is required to remove an electron from the outermost orbit.
So, the element with [Ne] $3 s^{2} 3 p^{3}$ configuration has highest ionisation energy.
