Question

Explain first ionic potential of nitrogen is greater than
first ip of oxygen

Answer 1

Answer:

Explanation:

So, the first ionization potential of nitrogen is higher than that of oxygen. As the electrons in nitrogen p-orbital are half-filled and are constant and need more energy to eliminate one electron.

Answer 2

Explanation:

N=1s2 ,2s2 ,2p3

o=1s2,2s2,2p4

in this case we see nitrogen has half filled p orbital which is stable electronic configuration as compared to 2p4 configuration of oxygen.so it is difficult to remove one electron from nitrogen for it's stable electronic configuration.But it is easy to remove electron from oxygen because it results a stable half filled configuration.Thats why the ionisation potential of nitrogen is grater than I.E of oxygen.
