Question

lonization potential of nitrogen is more than oxygen? Why?​

Answer 1

An atom is highly stable when its valence orbital is completely filled or half-filled and in nitrogen, the valence p orbital is exactly half filled. ... So, the ionization energy of nitrogen is more than that of oxygen.

Answer 2

Answer:

However, oxygen has one p-orbital with two electrons in, that repel each other. It is easier to remove one of these electrons than the unpaired electrons in nitrogen. This means less energy is required to remove an electron from oxygen and so nitrogen has a higher first ionisation energy.
