Nobelium - Nobelium Nobelium is a chemical element in the periodic table with the symbol No and atom number 102. History Nobelium was unambiguiously discovered and identified in April 1958 at UC Berkeley by A. Ghiorso, T. Sikkeland, J.R. Walton, and G.T. Seaborg, who used a new double-recoil technique. A heavy-ion linear accelerator (HILAC) was used to bombard a thin target of curium (95% 244Cm and 4.5% 246Cm) with 12C ions to produce 102No according to the 246Cm(12C, 4n) reaction. It is named after Alfred Nobel, the discoverer of dynamite and namesake of the Nobel Prize. In 1957 workers in the United States, Britain, and Sweden announced the discovery of an isotope of element 102 with a 10-minute half-life at 8.5 MeV, as a result of bombarding 244Cm.
Fermium - intense neutron irradiation of lower elements, such as plutonium, using a process of successive neutron capture interspersed with beta decays until these mass numbers and atomic numbers are reached. Sixteen isotopes of fermium are known to exist. 257Fm, with a half-life of about 100.5 days, is the longest lived. 250Fm, with a half-life of 30 minutes, has been shown to be a decay product of element 254-102. Chemical identification of 250Fm confirmed the production of element 102 (nobelium). Reference Los Alamos National Laboratory's Chemistry Division: Periodic Table - Fermium\n.
Elements song - names of all the chemical elements that were known at the time of writing, up to number 102, nobelium. It can be found as a track on An Evening Wasted With Tom Lehrer. The song is sung to the tune of Sir Arthur Sullivan's "Major General's Song" ("I am the very model of a modern major-general...") from The Pirates of Penzance. The song starts: There's antimony, arsenic, aluminum, selenium, And hydrogen and oxygen and nitrogen and rhenium ... and ends: ... These are the only ones of which the news has come to Harvard, And there may be many others but they haven't been discovered. Indeed, since that time, 11 more have been discovered, and 8 of those have been named..

Discoveries of the chemical elements - discovery because its short radioactive half-life had meant it was present in air in vanishingly tiny quantities. Once radium was available in macroscopic quantities, the production of this radioactive noble gas was readily detected as a product of radium's radioactive decay. Radon 1898 Fredrich Ernst Dorn who called it nitron Lutetium 1907 Georges Urbain Protactinium 1917 Kasimir Fajans, O. Göhring, Fredrich Soddy, John Cranston, Lise Meitner and Otto Hahn Hafnium 1923 Dirk Coster Rhenium 1925 Walter Noddack and Ida Tacke At this point, all the stable elements existing on earth had been discovered, and most of the periodic table had been filled. A few gaps remained amongst the higher mass elements, but there remained a troublesome gap at element number 43, just below manganese in the table. The gaps were filled.

Transuranium element - was first produced. 96. curium, Cm, named for Pierre and Marie Curie, famous scientists who separated out the first radioactive elements. 97. berkelium, Bk, named for the city of Berkeley, where the university is located. 98. californium, Cf, named for the state of California, where the university is located. Albert Ghiorso, who had been on Seaborg's team when they produced curium, berkelium, and californium, took over as director to produce: 99. einsteinium, Es, named for the great physicist Albert Einstein. 100. fermium, Fm, named for Enrico Fermi, the physicist who produced the first controlled chain reaction. 101. mendelevium, Md, named for the Russian chemist Dmitry Ivanovich Mendeleev, one of the two men who developed the periodic table of the chemical elements. 102. nobelium, No (see below). 103. lawrencium, Lr, named for.

One hundred two - number, and its factorization: makes it a sphenic number. It is the sum of four consecutive prime numbers (19 + 23 + 29 + 31). 102 is also: The atomic number of nobelium, an actinide. In the title of the movie 102 Dalmatians, starring Glenn Close.
