Amongst the elements with the following electronic configurations which one of them may have the hig — Periodic Table and Periodicity Chemistry Question

💡 Solution & Explanation

In general trend, ionization energy decreases down the group due to an increase in atomic radius and increases from left to right in periods due to a decrease in atomic size. Here, nitrogen (z=15) 2 3 Ne 3s 3p has the highest ionization energy as per the general trend and half-filled stability of p-orbitals.
