Because N is half filled and it is more stable then O thats why

Pratham Kochhar 8 years, 3 months ago

So oxygen would readily loose an electron to attain a stable configuration that is half filled configuration. So first Ionization energy of nitrogen is more than first ionization energy of Oxygen.
