Ununoctium
Ununoctium General
| Name:Ununoctium | Symbol:Uuo |
| Type:Noble Gas (perhaps) | Atomic weight:294 |
| Density @ 293 K:g/cm3 | Atomic volume:cm3/mol |
|
Discovered:
Ununoctium was first made by research scientists at the Joint Institute for Nuclear Research in Dubna, Russia in 2002. Scientists reacted calcium with californium ions. Ununoctium (Uuo) is a temporary element name until it is given an official name by The International Union of Pure and Applied Chemistry (IUPAC). As a result of its position in the periodic table ununtrium is expected to be classed as one of the noble gases. Too little of the element has been synthesized for this to be confirmed, although some calculations indicate ununoctium might in fact be a solid at room temperature. |
