Question

Which is the correct increasing order of ionization energies? (A)  N < O < F  (B)  F < O < N  (C)  N < F < O  (D)  O < N < F

The ionisation energy, in a period increases from left to right, hence, the increasing order should be N < O < F. But the actual order is O < N < F. The ionisation energy of nitrogen is greater than that of oxygen due to stabler electronic configuration of N ( 2p3, half-filled p-orbital).

Q. Which is the correct increasing order of ionization energies?

$N < O < F$

$F < O < N$

$N < F < O$

$O < N < F$
