Considering the fundamental rules for electron filling and quantum numbers, which of the following s — Atomic Structure Chemistry Question

💡 Solution & Explanation

A, B, and C correctly describe exchange energy stability, the Aufbau $(n+l)$ rule, and Pauli's exclusion principle. However, for a single-electron species (Hydrogen), energy depends exclusively on the principal quantum number $n$. Thus, the $4s$, $4p$, $4d$, and $4f$ orbitals are entirely degenerate (equal in energy). Therefore, statement D is false.
