hahnium造句

• Element 105 : joliotium; changed from hahnium.
• Element 108 : hahnium; changed from hessium.
• Consequently, hahnium has a chance of rejoining the periodic table, and even the French joliotium might make it into the pantheon.
• But why should such relativity effects alter the chemical properties expected for rutherfordium and hahnium, but not alter seaborgium the same way?
• But the international authority accepted only meitnerium for 109 . It shortened nielsbohrium to bohrium for 107 and named 108 hahnium, honoring Otto Hahn.
• This was a surprise because the chemistry of seaborgium's nearest lighter neighbors, rutherfordium and hahnium, does not fit the table nearly so neatly.
• The American team in 1997 proposed the name " hahnium " after Otto Hahn ( previously this name had been used for element 105 ).
• The American team proposed that the new element should be named " hahnium " ( Ha ), in honor of the German chemist Otto Hahn, the " father of nuclear chemistry ".
• Dropped from the union's previous list of provisional names are " joliotium " for Element 105, for the French physicist Frederick Joliot-Curie, and " hahnium " for Element 108, honoring the German physicist Otto Hahn.
• His original name for element 105 ( hahnium ) was changed by the International Union of Pure and Applied Chemistry ( IUPAC ) to dubnium, to recognize the contributions of the laboratory at Dubna, Russia, in the search for trans-fermium elements.
• An element naming controversy rose; consequently, " hahnium " was the name that most American and Western European scientists used and appears in many papers published at the time, and " nielsbohrium " was used in the Soviet Union and Eastern Bloc countries.
• The German group at the Gesellschaft f黵 Schwerionenforschung ( GSI ) in Darmstadt, who had ( undisputedly ) discovered elements 107 to 109, were dragged into the controversy when the Commission suggested that the name " hahnium ", proposed for element 105 by the Americans, be used for GSI's element 108 instead.
• No . 105 ( now to be called dubnium ) has gone for 25 years by the name hahnium ( for German physicist Otto Hahn, who won the Nobel prize for work on atomic fission . ) Even if the official name is dubnium, says Ghiorso, " we'll continue to use the name hahnium ."
• No . 105 ( now to be called dubnium ) has gone for 25 years by the name hahnium ( for German physicist Otto Hahn, who won the Nobel prize for work on atomic fission . ) Even if the official name is dubnium, says Ghiorso, " we'll continue to use the name hahnium ."
• In 1994 a committee of IUPAC recommended that element 108 be named " hahnium " ( Hn ) after the German physicist Otto Hahn, after an older suggestion of " ottohahnium " ( Oh ) so that elements named after Hahn and Lise Meitner ( meitnerium ) would be next to each other, honoring their joint discovery of nuclear fission.
• In particular, he said, further study might explain why seaborgium seems to have chemical properties consistent with its numerical place in the periodic table of elements, while the next two lighter elements, 104 ( rutherfordium ) and 105 ( hahnium ), which also exist only as the products of laboratory accelerators, seem chemically mismatched with their niches in the periodic table.
