An element has successive ionization enthalpies of , and . To which group of the modern periodic tab — Periodic Table and Periodicity Chemistry Question

💡 Solution & Explanation

A massive, sudden jump in successive ionization energies occurs between the 6th ($7870 \text{ kJ/mol}$) and 7th ($16000 \text{ kJ/mol}$) ionization enthalpies. This indicates that the 7th electron is being removed from a deeply buried, highly stable, fully filled noble gas core. Thus, the neutral atom has exactly 6 valence electrons, placing it in Group 16 (Chalcogen family).
