N/AUnbiquadium is the temporary systematic name for the undiscovered element with atomic number 124. It would be a superheavy element beyond the known periodic table and is treated entirely as a predicted nuclide family, not as an isolated material. Nuclear models place possible longer-lived isotopes near the proposed island of stability, but no isotope of element 124 has been confirmed experimentally.
This element has not been synthesized or experimentally confirmed. All listed physicochemical properties are calculated, extrapolated, or model-dependent.
