Question

Why does nitrogen have less electron affinity value compared to oxygen​

Answer 1

Answer:

Nitrogen has a half-filled p orbital. The number of electrons in the p orbital in nitrogen is three. Nitrogen, therefore, does not accept more electrons as it has a stable configuration. ... Therefore, nitrogen has a lower electron affinity than carbon and oxygen

Answer 2

Oxygen has a higher electron affinity than nitrogen because of its smaller size,higher nuclear charge and higher electronegativity.
