Question

Why nitrogen has greater ionisation energy than oxygen?​

Answer 1

Answer:

Now Ionisation energy(I.E) is the energy required to remove an electron from the valence shell of an atom.As seen in the configuration,N atom has stable half filled valence p-orbital ,therefore large amount of energy is required to remove the valence electron from N atom. Therefore I.E of N is higher than that of O.

Answer 2

Answer:

Ionization energy can be thought of as the energy required to remove an electron from the valence shell of an atom. Nitrogen is known to have a half-filled p-orbital and is quite stable. Therefore, the ionization of nitrogen will be higher than that of oxygen.
