Moscovium is a synthetic transactinide element in group 15, below bismuth. It has been made only atom by atom in heavy-ion fusion experiments, and all confirmed isotopes are highly radioactive and short-lived. Its chemistry has not been directly characterized in bulk; relativistic calculations predict a very heavy p-block metal with chemistry differing from lighter pnictogens, probably favoring the +1 and +3 oxidation states more than a stable +5 state.
Moscovium does not occur naturally in the Earth’s crust. The name moscovium and the symbol Mc, are the accepted ones for element 115. The name is in recognition of the Moscow region and honors the ancient Russian land that is home to the Joint Institute for Nuclear Research (JIRN), where the discovery experiments were conducted using the Dubna gas filled recoil separator in combination with the heavy ion accelerator capabilities of the Flerov Laboratory of Nuclear Reactions.
48Ca and 243Am were bombarded together in a cyclotron during a series of experiments from 14 July to 10 August 2003 (Fig. IUPAC.115.1). In February 2004, the results from these experiments were released in a report that stated “ununpentium” had been synthesized. This initial name means “115” in the IUPAC systematic naming scheme, which combines Latin and Greek names to produce un-un-pentium for 115. Moscovium has no known isotopic applications aside from scientific research.
On February 2, 2004, scientists working at the Joint Institute for Nuclear Research in Dubna, Russia, along with scientists from the U.S. Department of Energy's Lawrence Livermore National Laboratory and Oak Ridge National Laboratory, announced the creation of moscovium. In experiments performed between July 14, 2003 and August 10, 2003, atoms of americium-243 were bombarded with ions of calcium-48 using a device called a cyclotron. This produced one atom of moscovium-287 and three atoms of moscovium-288. All four atoms quickly decayed into other elements. Moscovium's most stable isotope, moscovium-289, has a half-life of about 220 milliseconds. It decays into nihonium-285 through alpha decay.
On Novemer 28th, 2016, element 115 was named Moscovium with the symbol Mc. Moscovium is the Moscow region of Russia, which is home to much of Russia’s superheavy element research. Muscovium was discovered by together by the Joint Institute for Nuclear Research, Dubna (Russia), Oak Ridge National Laboratory (USA), Vanderbilt University (USA) and Lawrence Livermore National Laboratory (USA).
No macroscopic sample of moscovium has ever been prepared, so its appearance is unknown. Calculations usually treat it as a dense metallic solid under ordinary conditions, but color, texture, melting point, and other bulk properties remain predicted rather than observed.
Moscovium has no practical commercial, industrial, medical, or consumer use. Its only use is in nuclear research, where individual atoms and their decay chains test models of superheavy-element stability, nuclear shell effects, and alpha-decay systematics. Moscovium isotopes are also important as links in decay chains leading to other superheavy nuclides, including nihonium produced by alpha decay of moscovium.
Since only a few atoms of moscovium have ever been produced, it currently has no uses outside of basic scientific research.
No confirmed compound of moscovium has been isolated or chemically characterized. Predictions place it in the pnictogen family but with strong relativistic effects that may make its valence behavior unlike that of nitrogen, phosphorus, arsenic, antimony, and bismuth. The +1 oxidation state is expected to be comparatively important, and +3 may also be accessible; +5 is predicted to be less stable. Hypothetical species such as moscovium(I) chloride, McCl, and moscovium(III) chloride, McCl₃, are discussed in theoretical chemistry only.
See more information at the Moscovium compound page.
The safety hazards of moscovium are dominated by radioactivity, not conventional chemical toxicity. Known isotopes decay mainly by alpha emission and spontaneous fission pathways within very short times, with isotope-specific half-lives. Quantities produced are far below macroscopic handling amounts, but any experiment requires heavy-element radiochemistry controls, shielding appropriate to decay products, and contamination prevention.
Moscovium has no confirmed natural occurrence and no environmental cycle. Atoms produced in laboratories decay rapidly to daughter nuclides, so persistence as moscovium in air, water, soil, or organisms is not expected. Any environmental relevance would be limited to controlled accelerator facilities and the management of radioactive targets, residues, and decay products.
Moscovium has no commodity market, no industrial supply chain, and no recoverable stock. It is produced only in specialized accelerator experiments by bombarding rare actinide targets with heavy ions, for example using americium targets and calcium beams. The limiting factors are accelerator time, target preparation, nuclear reaction cross sections, detector capability, and radiological controls, not ordinary mining, refining, demand, or substitution economics.
Made by bombarding americium-243 with calcium-48.
Moscovium is not expected to have a lasting natural cosmic abundance. Any atoms formed in energetic nucleosynthesis or high-energy particle events would decay quickly compared with astronomical timescales. It has not been identified in stars, meteorites, planets, or interstellar material; its significance is mainly as a laboratory probe of the superheavy region near predicted nuclear shell stabilization.
- The first published moscovium decay chains were produced using ²⁴³Am targets and ⁴⁸Ca projectiles.
- Its name refers to the Moscow region, recognizing the role of the Joint Institute for Nuclear Research in Dubna.
- Moscovium isotopes can decay to nihonium by alpha emission.
- Only a few atoms are needed to establish a decay chain, but repeated events are required for confident assignment.
- Its periodic-table position suggests group 15 chemistry, yet relativistic effects are expected to be large.
