Hello, There you go. The French chemist Paul-Emile Lecoq de Boisbaudran (1838â1912), who discovered it in 1875. Gallium (Latin Gallia meaning Gaul; also gallus, meaning rooster) was discovered spectroscopically by Lecoq de Boisbaudran in 1875 by its characteristic spectrum (two violet lines) in an examination of a zinc blende from the Pyrenees.
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.
