The Element Ununoctium


"The Atom"

The Ununoctium Element
Elements can be classified based on their physical states (States of Matter) e.g. gas, solid or liquid. This element is a solid. This extremely unstable element is a radioactive, synthetic transactinide element and is artificially produced. Ununoctium is currently the only synthetic member of Group 18. It has the highest atomic number and highest atomic mass of all the elements discovered to date. Ununoctium is a temporary name taken from Latin meaning one-one-eight. It is not found free in the environment as it is a synthetic element. The Atomic Number of this element is 118 and the Element Symbol is Uuo.

History and Discovery of the Ununoctium Element
The element was discovered on July 19, 2000 by scientists working at the Joint Institute for Nuclear Research in Dubna, Russia together with scientists from the U.S. Department of Energy's Lawrence Livermore National Laboratory.

The scientists produced ununoctium by bombarding atoms of californium-249 with ions of calcium-48. This produced ununoctium-294, an isotope with a half-life of about 0.89 milliseconds (0.00089 seconds), and three free neutrons. The californium target was irradiated with a total of 1.6*1019 calcium ions over the course of 1080 hours, resulting in the production of three atoms of ununoctium.

Ununoctium currently has no uses outside of basic scientific research.

Ununoctium - IUPAC and the Modern Standardised Periodic Table
The Standardised Periodic Table in use today was agreed by the International Union of Pure Applied Chemistry, IUPAC, in 1985 and now recognises more periods and elements than Dimitri Mendeleev knew in his day but still all fitting into his concept of  the "Periodic Table" in which Ununoctium is just one element that can be found.
