[edit] History
The name unbioctium is used as a placeholder, as in scientific articles about the search for element 128. Transuranic elements (those beyond uranium) are, except for microscopic quantities and except for plutonium, always artificially produced, and usually end up being named for a scientist or the location of a laboratory that does work in atomic physics (see systematic element name for more information).
[edit] 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.
[edit] Properties
The physical properties of unbioctium have not yet been investigated, though this element is expected to be highly reactive and oxidize quickly. This element would presumably be a metal and solid. The color would probably be silvery white.
