HistoryUnunseptium was first made by research scientists at the Joint Institute for
Nuclear Research in Dubna, Russia in 2010. Scientists reacted calcium with berkelium ions.
Ununseptium (Uus) is a temporary element name until it is given an official name
by The International Union of Pure and Applied Chemistry (IUPAC). As a result of
its position in the periodic table ununseptium is expected to be classed as one
of the halogens. The effects of relativistic electrons may result in partial
metalloid properties. Too little of the element has been synthesized for the
chemical properties to be confirmed
