Copernicium
The only accolade that American chemist Glen T. Seaborg cared for more than winning the Nobel Prize was having an element named in his honor. In 1994 his colleagues gave him that distinction, elevating the Nobel laureate to the status of helium and hydrogen. Over the next fifteen years, six more elements followed seaborgium onto the periodic table, bringing the total to 112. The last, enshrined in 2009, pays homage to Nicolas Copernicus. Unlike Seaborg, Copernicus never sought such a tribute. Having already scored ample name recognition with the Copernican Revolution, he didn’t really need it. If anything, by the time copernicium was recognized as an element, the periodic table needed him. Copernicium is one of twenty elements containing more protons than the ninety-two naturally found in uranium. All twenty are made artificially in laboratories by colliding preexisting elements such as zinc and lead in a particle accelerator or cyclotron. In some ten billion billion bombardments, two protons will fuse to make one atom of a new super-heavy element. Typically the atom is unstable, lasting perhaps a millisecond before decaying into lighter elements again. All of which makes element fabrication a tricky enterprise, nearly as miraculous as alchemy and considerably more contentious. Who synthesized the first atom of an element, and therefore gets to name it? Seaborg’s UC Berkeley laboratory was the only one in the business through the 1940s and 1950s, netting him ten elements, including plutonium, for which he won the 1951 Nobel Prize in Chemistry. By the 1960s, however, there was competition from the Soviets, resulting in the so-called Transfermium Wars. For several decades the periodic table became a political battlefield rather than an intellectual commons. Nothing could have been further from the table’s Enlightenment origins. The product of empirical research and intended to disseminate universal knowledge, a table of presumed elements was first published by the French chemist Antoine Lavoisier in 1789, arranging thirty-three substances, including silver and sulfur and phosphorus, based on observed attributes (such as “Oxydable and Acidifiable simple Metallic Bodies”) rather than according to philosophical precepts.
