moscovium

Moscow +‎ -ium, named after Moscow Oblast. Promulgated as the proposed name for ununpentium in June 2016 by the IUPAC based on recommendations of the Joint Institute for Nuclear Research, Oak Ridge National Laboratory, Vanderbilt University and Lawrence Livermore National Laboratory to honor the region where the element was discovered.

     In January 2016 the International Union of Pure and Applied Chemistry (IUPAC) announced the discovery of four new elements, so completing the seventh row of the periodic table. They have since been named as nihonium, Nh, muscovium^[sic], Mc, tennessine, Ts, and organesson^[sic], Og. The procedures for naming new elements are clearly laid out by IUPAC.

   • 2019 February 27, Emily Conover, “Extreme elements push the boundaries of the periodic table”, in Science News‎:

     Researchers carefully choose the makeup of the beam and the target in hopes of producing a designer atom of the element desired. That’s how the four newest elements were created: nihonium (element 113), moscovium (115), tennessine (117) and oganesson (118) (SN Online: 11/30/16).
