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).

Stability

The element unbioctium would likely have isotopes that have relatively long half life, possibly on the order of 10⁵ years, as this element is very close to an island of stability. An estimated five isotopes have half lives of over a year while Ubo-340 is the most stable.

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.
