Question

Why successive ionization enthalpies of nitrogen decreases

Answer 1

Ionization Energy Trends in the Periodic Table. The ionization energy of an atom is the amount of energy required to remove an electron from the gaseous form of that atom or ion. ... Successive ionization energies increase in magnitude because the number of electrons, which cause repulsion, steadily decrease.

Answer 2

Successive ionization energies increase in magnitude because the no. of electons, which cause repulsion steadily decrease. This is not a smooth curve there is a big jump in ionization energy after the atom has lost its valency electrons.
