Ununoctium
Ununoctium is the temporary name of a retracted chemical element in the periodic
table that has the temporary symbol Uuo and has the atomic number 118.
In 1999 , researchers at Lawrence Berkeley National Laboratory announced the
discovery of elements 116 and 118, in a paper published in Physical Review
Letters. The following year, they published a retraction after other
researchers were unable to duplicate the results. In June 2002, the director of
the lab announced that the original claim of the discovery of these two elements
had been based on data fabricated by principal author Victor Ninov .
The name Ununoctium is used as a placeholder, such as in scientific articles
about the search for Element 118; it is Dog Latin "one-one-eight-ium" ("ium"
being a standard ending for element names). Such transuranic elements are always
artificially produced, and usually end up being named for a scientist or the
town of their discovery á la Darmstadtium. See Element naming controversy ,
systematic element name .
Ununoctium would probably share
the properties of its group, the noble gases, resembling Radon in its chemical properties.
Ununoctium doesn’t occur naturally, it has not been found
in the earth’s crust, so there is no reason to consider its health hazards.
