An element has the atomic number . What is its designated IUPAC group number (from 1 to 18) in the m — Periodic Table and Periodicity Chemistry Question

💡 Solution & Explanation

Elements with atomic numbers between 104 and 118 complete the 7th period. The group number for these superheavy elements directly corresponds to the last two digits of their atomic number. Thus, for $Z=116$, the group number is 16 (Chalcogen family).
