The atom has empty d-orbitals.
Explanation: Atoms in period 3 or beyond (e.g., P, S, Cl) can use available d orbitals to accommodate more than eight electrons and form expanded octets. (Note: advanced treatments sometimes describe hypervalence without invoking d‑orbitals explicitly, but the standard conceptual requirement taught is accessible d orbitals.)
