Ununbium Element 112: Properties and Discovery

[Orion1]

Ununbium is a temporary IUPAC systematic element name for a chemical element in the periodic table that has the temporary symbol Uub and the atomic number 112.

Element 112 is the latest superheavy element to be officially recognised by IUPAC. The most stable isotope discovered to date is 285 112 with a_half-life of ~30 s. In total, about 60 atoms of Ununbium have been detected using various nuclear reactions. An unconfirmed isotope, 285 112, has a possible_half-life of ~9 minutes, and would be one of the longest-lived superheavy isotopes known to date.

Recent experiments strongly suggest that element 112 behaves as a typical member of group 12, demonstrating properties consistent with a volatile metal.

In May 2009, the JWP reported on the claims of discovery of element 112 again and officially recognised the GSI team as the discoverers of element 112. This decision was based on recent confirmation of the decay properties of daughter nuclei as well as the confirmatory experiments at RIKEN.

This was discovered in 1996. Why are you posting this now?
