New additions to the periodic table are artificial elements forged in laboratories that are so unstable they exist for just fractions of seconds. The names for elements 110, 111 and 112 - darmstadtium, roentgenium and copernicium, respectively - had already been approved by the International union of pure and applied chemistry(IUPAC).
These are large super heavy elements ,that can only be created in the laboratory and quickly break down into other elements.....
You may even own a periodic table containing these names. It wasn't until Friday, however, that physicists attending the annual meeting of the International Union of Pure and Applied Physics (IUPAP) in London rubber-stamped these choices and the accompanying symbols: Ds, Rg and Cn. This completes the final stage of the official element naming process - for now.
Copernicium ,discovered in1996,was named after astronomer,Nicolaus copernicus and roentgenium,discovered in1994,has been named for physicist Wilhelm roentgen...
"The proposed names will be released for public review in the not too distant future," says John Corish of the University of Dublin, who is a member of IUPAC."
