Question

Elements like N and P have high ionization enthalpies. Why? ​

Answer 1

Answer:

Both these elements have the configurations in which all the orbitals of the same sub-level are exactly half-filled. Such an arrangement gives extra stability to the atom. As a result, the removal of electron becomes difficult and hence they have high value of ionisation enthalpies.

Answer 2

Explanation:

hi

You know the maximum capacity of p orbital is 6 electrons. ... Since Nitrogen is half filled coz it has 3 electrons out of 6 electrons that can be occupied in p orbital it has higher ionization energy compared to that of oxygen.
