- The element nobelium, via It's elemental website, Sept. 10, 2012(No; Nobelium; Atomic Number: 102; Atomic Weight: 259; Phase at Room Temperature: Solid; Element Classification: Metal; Period Number: 7; Group Number: none; Group Name: Actinide; radioactive and artificially produced; Nobelium's most stable isotope, nobelium-259, has a half-life of about 58 minutes. It decays into fermium-255 through alpha decay or into mendelevium-259 through electron capture.)
- Wikipedia, Sept. 10, 2012(Nobelium is a synthetic element with the symbol No and atomic number 102. It was first correctly identified in 1966 by scientists at the Flerov Laboratory of Nuclear Reactions in Dubna, Soviet Union. Little is known about the element but limited chemical experiments have shown that it forms a stable divalent ion in solution as well as the predicted trivalent ion that is associated with its presence as one of the actinides; Naming: Element 102 was first named nobelium (No) by its claimed discoverers in 1957 by scientists at the Nobel Institute in Sweden. The name was later adopted by Berkeley scientists who claimed its discovery in 1959. The International Union of Pure and Applied Chemistry (IUPAC) officially recognised the name nobelium following the Berkeley results. In 1994, and subsequently in 1997, the IUPAC ratified the name nobelium (No) for the element on the basis that it had become entrenched in the literature over the course of 30 years and that Alfred Nobel should be commemorated in this fashion.)
- Wikipedia, Sept. 18, 2012(under Dubnium: in 1994, the IUPAC proposed the name joliotium (Jl) [for dubnium], after the French physicist Frédéric Joliot-Curie, which was originally proposed by Soviet team for element 102, later named nobelium)
