Moscovium is a radioactive , synthetic element about which trivial is know . It is classified as a metal and is expected to be self-coloured at elbow room temperature . It decays quickly into other element , including nihonium .
The factor had previously been intend ununpentium , a proxy name that means one - one - five in Latin . In November 2016 , the International Union of Pure and Applied Chemistry ( IUPAC)approved the name moscoviumfor element 115 .
Moscovium
The IUPAC also sanction name for elements 113 ( nihonium , with atomic symbol Nh ) , 117 ( tennessine , Ts ) and 118 ( oganesson , Og ) .
figure for element 115 and 117 were proposed by their discoverers at the Joint Institute for Nuclear Research in Dubna , Russia ; the Oak Ridge National Laboratory in Tennessee ; Vanderbilt University in Tennessee ; and Lawrence Livermore National Laboratory in California . Both element gens , moscovium and tennessine , honor region where experimentation linked to creating the element took shoes .

Discovery
Moscovium was discovered in 2003 and formally announced on Feb. 2 , 2004 . It was created and foretell by scientist at the Joint Institute for Nuclear Research in Dubna , Russia , and scientist at the Lawrence Livermore National Laboratory in the United States .
Properties
Moscovium has four isotope with known half - lives , the most stable of which is289Mc , with a half - live of about 220 msec .
The nuclear weight for manmade transuranium element is found on the longest - lived isotope . These atomic weight should be take provisional since a new isotope with a longer half - life could be produced in the future . [ SeePeriodic Table of the Elements ]
Sources of moscovium
To make moscovium , the scientists in Russia and the United States bombard atoms ofamericiumwith ions ofcalciumin a cyclotron . This grow four atoms of moscovium .
Uses of moscovium
Only a few atoms of moscovium have ever been made , and they are only used in scientific work . It is used to make nihonium .
