[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, 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 relatively long half life as this element is very close to island of stability, possibly on the order of 10⁵ years. An estimated five isotopes have half lives of over a year while Ubo-340 is 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.
