Lv

Moscovium (Mc) is element 115 on the periodic table. Atomic mass of Mc: 290.0000 u. Mc is in period 7, group 15. Melting point of Mc: 700.00 K.Density of Mc: 13.50 g/cm³.

Why Moscovium Matters

Moscovium in everyday life and industry

In Your Home

  • No commercial applications
  • Research element only
  • Very few atoms ever produced
  • Half-life under 1 second

In Your Body

✗ Not essential

No biological role. Too unstable for any studies.

Safety: Moscovium is radioactive. Would presumably be toxic.

Common Misconceptions

Wrong:Moscovium is named after Moscow city.
Correct:Moscovium honors Moscow Oblast (the region), where JINR Dubna is located, not just the city.
Wrong:Moscovium was a purely Russian discovery.
Correct:Moscovium was discovered through Russian-American collaboration between JINR Dubna and LLNL.
Wrong:The seventh period has always been complete.
Correct:Moscovium was one of four elements (Nh, Fl, Mc, Lv, Ts, Og) that completed the seventh period in 2016.
