Question

First ionization potential of nitrogen and oxygen which will be greater

Answer 1

Answer:

That's why ionisation energy of Nitrogen is more than Oxygen. Answer: This is so because nitrogen has half filled electronic configuration. This energy will be higher for fully filled and half-filled electronic configuration than partially filled electronic configuration.

Thanks.

Answer 2

Answer:

first Ionization energy of nitrogen is more than first ionization energy of Oxygen. ... Oxygen has low ionisation energy (than that of nitrogen). It is due to an electron being added to an already half full orbital in oxygen, which results in electron electron repulsion, which will lower the ionisation energy
