What is Nobelium?
Alfred Nobel, a Swedish chemist who lived from 1833 to 1896, is known for discovering dynamite and through his happiness to introduce a prestigious group of awards known as the Nobel Prize. It is less known that after him a synthetic element with atomic number 102, nobelium, was named. Nobelium was discovered in 1957, in addition to the last transuranic actinoids to be discovered.
The discovery of Nobelium has an interesting history. His discovery announced in 1957 physics at the Nobel Institute in Sweden. The discovery was carried out as a result of the bombing of Kuririum with carbon cores and confirmed in several other laboratories, with the proposed Nobelium. But then the finding was downloaded. In 1958, the team at the University of California at Berkeley, tried again, this time using carbon ions, and although they could not confirm earlier news, they finally managed to create an isotop 102. Due to the selection of the name - the navrHli that the original designation of Nobelia and without a booth, and so it was. However, newer investigation in 1992 showed that while the Berkeley team could detect element 102, the first definitive detection of April in 1966 and the International Union of Pure and Applied Chemistry (IUPAC) recognizes scientists from April as discoverers.
April scientists designed the name Joliotium with the symbol Jo as recognition of Frédéric Yoliot-Curie, but this name was not used. For a short time, the name Flovium with the atomic symbol of FL was used on the IUPAC design to refer to the element. However, this was replaced by the recognition of IUPAC that the name of the Nobelium, which was used for 30 years, has been extended throughout the literature and should be kept, both for this reason for this reason Nobel.
Nobelium was synthesized from the disintegration of elements that are heavier, including Hassia, Lawrenia, Rutherfordium and Seaborgium. However, there are insufficient amounts of nobelium that either creates a hazardBakes radiation - which would do in sufficient quantities - or to describe such aspects as its appearance.
Seventeen isotopes have been described, with the most stable-nobelium-259-S half a life of 58 minutes. Other isotopes are expected to have a longer half -life. The disputes that surround its original discovery have spread to the discovery of its isotopes. The 2003 scientists' claims from Flerova's Nuclear Reaction Laboratory (FLNR) to find that the lightest isotope has been inserted so far when the Nobelium-249 intimation was found to be caused by the Nobelium-250.
