What is the absolute maximum number of electrons that can be accommodated in all the completely fill — Atomic Structure Chemistry Question

💡 Solution & Explanation

The combination $n=4, l=3$ refers specifically to the $4f$ subshell. The number of degenerate orbitals is $(2l+1) = 7$. Since each orbital holds a maximum of $2$ electrons, the maximum capacity is $7 \times 2 = 14$ electrons.
