The electron in the same orbital may be identified with the quantum number — Atomic Structure Chemistry Question

💡 Solution & Explanation

An orbital is uniquely defined by three spatial quantum numbers: principal (n), azimuthal (l), and magnetic (m). According to Pauli's Exclusion Principle, two electrons in the same orbital must have opposite spins. Therefore, they differ in their spin quantum number (s), which allows us to identify or distinguish between them.
