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 - 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.
