Copernicium
Copernicium (Cr) is a radioactive metal that has the atomic number 112 in the periodic table, its appearance is not fully known due to the minuscule amounts produced of it. It is a Transition metal in Group 11. It has the symbol Rg.
Copernicium is a chemical element created in the laboratory with radioactive properties. Copernicium has a half life of around 28 seconds. It is name after the astronomer Nicolaus Copernicus. It was discovered in Darmstadt, Germany, at the Institute for Heavy Ion Research in 1996. A team led by Sigurd Hofmann and Victor Ninov. As so little of it has been created the melting and boiling point have not been analysed.
