Ts

Livermorium (Lv) is element 116 on the periodic table. Atomic mass of Lv: 293.0000 u. Lv is in period 7, group 16. Melting point of Lv: 700.00 K.Density of Lv: 12.90 g/cm³.

Why Livermorium Matters

Livermorium in everyday life and industry

In Your Home

  • No commercial applications
  • Research element only
  • Only about 30 atoms ever made
  • Half-life in milliseconds

In Your Body

✗ Not essential

No biological role. Too unstable for studies.

Safety: Livermorium is radioactive. Would presumably be toxic.

Common Misconceptions

Wrong:Lawrence Livermore National Laboratory is in Nevada.
Correct:Livermore is in California, about 50 miles east of San Francisco, not in Nevada.
Wrong:LLNL only does weapons research.
Correct:The lab does both nuclear weapons research and civilian science, including significant contributions to superheavy element discovery.
Wrong:Livermorium behaves exactly like polonium.
Correct:Livermorium might behave quite differently from polonium due to strong relativistic effects on its electron orbitals.
