Moscovium is in the center of the theoretical island of stability. No stable isotopes of moscovium have yet been found. Models predict that the stable isotope of ununpentium should have 184 neutrons. The stable isotope with 184 neutrons is 299Uup. The isotope that has been made ha).
History[change | change source]
On February 2, 2004 a report that moscovium and ununtrium were made was written in a journal named Physical Review C. The report was written by a team of Russian scientists at Dubna University's Joint Institute for Nuclear Research and American scientists at the Lawrence Livermore National Laboratory.,
Scientists of Japan also report that they have made moscovium.
Name[change | change source]
The name was changed to Moscovium. It used to be named ununpentium
Chemical properties[change | change source]
Moscovium is in the same group as bismuth but its chemical properties will be different. The chemistry of ununpentium will be very influenced by special relativity. It will make its properties different to the other elements in the periodic table that have a smaller atomic number. One important difference from bismuth is the presence of a stable oxidation state of +I (Uup+). The (Uup+) ion is thought to have chemical properties like Tl+.
In popular culture[change | change source]
The most popular story about moscovium is from Bob Lazar. It is not pseudoscience because it is a refutable theory, however Lazar's claims are not backed by any direct experimental evidence at this time.
