Question

why is the ionization enthalpy of group 15 very large ?​

Answer 1

Answer:

Explanation:

In group 15, the valence electrons are 5 which gives the electronic configuration . Here, the p-orbital is half filled and is in the most stable configuration. Therefore, removing an electron from this orbital will not be favorable. Hence, to remove an electron it requires more energy.
