SUMMARY

Ununbium, also known as element 112, is a superheavy element with the atomic number 112 and the temporary symbol Uub. Officially recognized by IUPAC in May 2009, it was discovered by the GSI team, with the most stable isotope being 285 112, which has a half-life of approximately 30 seconds. Recent experiments indicate that Ununbium behaves like a typical member of group 12, exhibiting properties consistent with volatile metals. A potential unconfirmed isotope, 285 112, may have a half-life of around 9 minutes, making it one of the longest-lived superheavy isotopes known.

PREREQUISITES
  • Understanding of IUPAC nomenclature for chemical elements
  • Knowledge of nuclear reactions and isotope stability
  • Familiarity with the periodic table and group classifications
  • Basic principles of radioactive decay and half-life calculations
NEXT STEPS
  • Research the properties of group 12 elements in the periodic table

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?
 
Orion is the most mysterious guy I know hehe
