底下是我們系上教授寄給全系的通告信部分內容 原子序112的元素在1996年就被發現 但是到底是德國還是美國的團隊先發現的? 吵了14年 就在今年2月19日 IUPAC在哥白尼誕辰537年把榮耀歸給了德國團隊 也依照德國團隊的提案 將元素命名為Copernicium(簡寫Cn)以紀念哥白尼 至於元素113-118到底誰先發現? 還在戰 (118應該沒甚麼好吵的吧 膝蓋都跪下去了...) 俊毅Bird Man ------------------------------------------------------------------------------ There is a new element in town and it is named after the sixteenth-century Polish scientist Nicholas Copernicus. Copernicium is element 112 and its symbol is Cn. A heavier member of the Zn-Cd-Hg family, Cn was first seen in 1996 by researchers at the Society for Heavy Ions Research in Darmstadt, Germany, after they bombarded a lead target with zinc ions. It took the International Union of Pure and Applied Chemistry, which regulates nomenclature, nearly fourteen years to resolve the dispute between the German and American researchers over who first produced the new element. In the March issue of the journal Pure and Applied Chemistry, IUPAC declared that the Germans made the discovery first and are thus entitled to propose a name. Physicist Sigurd Hofmann, leader of the German team, said that the intent was to "salute an influential scientist who did not receive any accolades in his own lifetime, and highlight the link between astronomy and the field of nuclear chemistry." Copernicus was the first scientist to conclude that the planets of the solar system revolve around the sun rather than around the Earth. The IUPAC has not yet resolved competing claims over the discovery of elements 113 through 118. ------ Reference: K. Tatsumi1 and J. Corish. Pure Appl. Chem., Vol. 82, No. 3, pp. 753-755, 2010. --
