nobelium उदाहरण वाक्य

The activity was initially assigned to 254 No but later changed to 252 No . However, they also noted that it was not certain that nobelium had been produced due to difficult conditions.
Similarly, nobelium was produced at the Joint Institute for Nuclear Research, Dubna, Russia, in 1965 in several reactions, one of which included irradiation of 243 Am with 15 N ions.
Among these exotics is mendelevium, after Dmitry I . Mendeleyev, the 19th-century Russian chemist who invented the periodic table, and nobelium, for the bestower of science's big prize.
In addition to plutonium, he is credited as a lead discoverer of americium, curium, and berkelium, and as a co-discoverer of californium, einsteinium, fermium, mendelevium, nobelium and seaborgium.
Elements discovered by Berkeley Lab physicists include astatine, neptunium, plutonium, curium, americium, berkelium *, californium *, einsteinium, fermium, mendelevium, nobelium, lawrencium *, dubnium, and seaborgium *.

The American synthesis was independently confirmed in 1973 and secured the identification of rutherfordium as the parent by the observation of K-alpha X-rays in the elemental signature of the 257 Rf decay product, nobelium-253.
However, if a direct " catcher " gold foil is used, the process is complicated by the need to separate out the gold using anion-exchange chromatography before isolating the nobelium by elution from chromatographic extraction columns using HDEHP.
Among the transuranium elements, this restriction was relaxed, there followed curium ( after the Curies ), einsteinium, fermium ( Enrico Fermi ), mendelevium ( Dmitri Mendeleev ), nobelium, and lawrencium ( after Ernest Lawrence ).
""'The Elements "'" is a song by musical humorist and lecturer Tom Lehrer, which recites the names of all the chemical elements known at the time of writing, up to number 102, nobelium.
In 1986, nobelium metal was estimated to have an enthalpy of sublimation between 126 kJ�mol " 1, a value close to the values for einsteinium, fermium, and mendelevium and supporting the theory that nobelium would form a divalent metal.
