Unbioctium is the temporary name of a hypothetical undiscovered element on the periodic table that has the temporary symbol Ubo and atomic number 128. Unbioctium is also known as eka-curium. To date, no attempt has ever been made to synthesize unbioctium.

Predicted compounds
Unbioctium may form a hydroxide [Ubo(OH)3], and an oxide [Ubo2O3] like curium.

Stability
The element unbioctium would likely have isotopes that have a half life of only a few milliseconds, as this element is very close to an island of stability. An estimated five isotopes would then have half lives of over a half second while Ubo-340 would be the most stable.

Properties
The physical properties of unbioctium, if it exists, are unknown, though this element may be expected to be highly reactive and oxidize quickly. It would presumably be a metal and solid. The color would probably be silvery white.
