N/AUnbitrium is the temporary systematic name for element 123, a hypothetical superheavy element beyond the confirmed periodic table. It has not been synthesized or identified in nature. Chemical discussions of Ubt are therefore predictive and model-dependent. It is expected to belong to the superactinide region of period 8, where relativistic effects and overlapping 5g, 6f, 7d, and 8s orbital energies make simple extrapolation from lighter elements unreliable.
This element has not been synthesized or experimentally confirmed. All listed physicochemical properties are calculated, extrapolated, or model-dependent.
