'''Unbioctium''' ({{IPAc-en|icon|ˌ|uː|n|b|aɪ|ˈ|ɒ|k|t|i|əm}}) is the temporary name of a hypothetical undiscovered [[chemical element|element]] on the [[periodic table]] that has the temporary symbol Ubo and [[atomic number]] 128.{{Citation needed|date=February 2010}} 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)<sub>3</sub>], and an oxide [Ubo<sub>2</sub>O<sub>3</sub>] 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.{{Citation needed|date=August 2009}} |
|||
== 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.{{Citation needed|date=February 2010}} |
