The element was named Copernicium in July 2009. Formerly it was known under the systematic IUPAC name Ununbium (system explained here).
Background of the naming after Nicolaus Copernicus from Stuart Fox, Newly Discovered Element 112 Named "Copernicum", from PopSci
By choosing to honor the father of the heliocentric solar system, element 112 discovery team leader Sigurd Hofmann wanted to avoid the divisive names selected for past elements, salute an influential scientist who didn't receive any accolades in his own lifetime, and highlight the link between astronomy and Hofmann's own field of nuclear chemistry.The symbol is Cn. There was first thought of Cp, but that has been in use for Cassiopeium, now Lutetium.
The new element 112 was produced and identified unambiguously in an experiment at SHIP, GSI Darmstadt. Two decay chains of the isotope 277112 were observed in irradiations of 208Pb targets with 70Zn projectiles of 343.8 MeV kinetic energy. The istope decays by emission of alpha particles with a half-life of (240 +430 -90) micro seconds. Two different alpha-energies of (11,649+-20)keV and (11,454+-20) keV) were measured for the decaying nuclei. The cross section measured in three weeks of irradiation is (1.0 +1.3 -0.6) pb.
IUPAP/IUPAC Joint working party assessment: The results of this study are of characteristically high quality but there is insufficient internal redundancy to warrant conviction at this stage. Confirmation by further results is needed to assign priority of discovery to this collaboration (Karol et al., 2001, 964).
Nicolaus CopernicusNicolaus Copernicus (Toruń (Thorn), 19 February 1473 – Frombork (Frauenburg), 24 May 1543) was the first astronomer to formulate a comprehensive heliocentric cosmology, which displaced the Earth from the center of the universe.
Copernicus' epochal book, De revolutionibus orbium coelestium (On the Revolutions of the Celestial Spheres), published just before his death in 1543, is often regarded as the starting point of modern astronomy and the defining epiphany that began the scientific revolution. His heliocentric model, with the Sun at the center of the universe, demonstrated that the observed motions of celestial objects can be explained without putting Earth at rest in the center of the universe. His work stimulated further scientific investigations, becoming a landmark in the history of science that is often referred to as the Copernican Revolution.
Among the great polymaths of the Renaissance, Copernicus was a mathematician, astronomer, physician, quadrilingual polyglot, classical scholar, translator, artist, Catholic cleric, jurist, governor, military leader, diplomat and economist. Among his many responsibilities, astronomy figured as little more than an avocation — yet it was in that field that he made his mark upon the world. (note).
