Barium was discovered by Sir Humphrey Davy at 1808 in England. Origin of name: from the Greek word barys meaning heavy Baryta (barium oxide, BaO) was distinguished from lime (calcium oxide, CaO) by Scheele in 1774.
Copernicium was discovered during fusion experiments at the Centre for Heavy Ion Research in Germany in 1996. The name was proposed by Prof Sigurd Hofmann. Under the IUPAC rules, his team were forbidden from naming the element after a living person. 'After IUPAC officially recognised our discovery, we â that is all scientists involved in the discovery â agreed on proposing the name copernicium for the new element 112. 'We would like to honour an outstanding scientist who changed our view of the world,' said Prof Hofmann, head of the discovering team.
