nielsbohrium การใช้

• They had suggested the names nielsbohrium, hassium and meitnerium.
• Element 107 : bohrium; changed from nielsbohrium.
• But the international authority accepted only meitnerium for 109 . It shortened nielsbohrium to bohrium for 107 and named 108 hahnium, honoring Otto Hahn.
• The Soviet team proposed the name " nielsbohrium " ( Ns ) in honor of the Danish nuclear physicist Niels Bohr, one of the founders of the theories of the atomic structure and the quantum theory.
• In 1994 a committee of IUPAC recommended that element 107 be named " bohrium ", not " nielsbohrium ", since there was no precedence for using a scientist's complete name in the naming of an element.
• The German team joined with the Soviet team in that it suggested the name " nielsbohrium " for the new element, believing Bohr did deserve an element named after him, and hoping to ease the tension on the element 105 controversy.
• 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.
• For element 105, they proposed the name " joliotium " ( Jl ), after the French physicist Fr閐閞ic Joliot-Curie, a significant contributor to the development of nuclear physics and chemistry; this name was originally proposed by the Soviet team for element 102, which by then had long been called nobelium . ( The name " nielsbohrium " for the element 107 transformed to " bohrium " to conform the practice set by all then-current elements . ) These names were to be accepted on a Council meeting in 1995.
