Moscovium was synthesized in 2003 by JINR Dubna with US collaborators using americium-243 targets and calcium-48 ions. The name honors Moscow Oblast, where JINR is located.
Moscovium-289
Half-life: About 0.22-0.41 seconds. Short-lived isotope that decays by alpha emission toward nihonium; values vary by source.Moscovium-290
Half-life: About 0.65-0.84 seconds. Longest-lived commonly cited moscovium isotope; decays toward nihonium-286.- Superheavy nuclear decay-chain research
- Parent-decay routes that help identify nihonium isotopes
- Theoretical Group 15 chemistry below bismuth
- Relativistic inert-pair effect studies
Moscovium has no biological role. It is synthetic, radioactive and exists for fractions of a second.
- Moscovium decay chains helped independent teams connect element 115 work with nihonium nuclei.
- Its chemistry has not been experimentally characterized, but calculations compare it with bismuth.
- The element name recognizes the Moscow region, a major center of superheavy element research.
- Moscovium has atomic number 115 and symbol Mc.
- Its predicted electron configuration is [Rn] 5f¹⁴ 6d¹⁰ 7s² 7p³.
- Moscovium is a Group 15 superheavy element below bismuth.
- Remember Mc-290 for decay chains leading to nihonium-286.
