According to the Aufbau principle, each period begins with the filling of a new principal quantum sh — Periodic Table and Periodicity Chemistry Question

💡 Solution & Explanation

The 6th period starts filling from $n=6$. The order of subshell filling is $6s$, $4f$, $5d$, $6p$. The maximum capacity of these subshells is $2 (s) + 14 (f) + 10 (d) + 6 (p) = 32$ electrons, meaning 32 elements are accommodated in this period.
