History and Discovery of the Ununseptium Element
The element was discovered in January 2010 by scientists working at the scientists at the Flerov Laboratory of Nuclear Reactions. The scientists produced Ununseptium by bombarding atoms of berkelium-249 with ions of calcium-48.
Ununseptium currently has no uses outside of basic scientific research.

Ununseptium - 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 in his day but still all fitting into his concept of the "Periodic Table" in which Ununseptium is just one element that can be found.
