Flerovium (Fl) is element 114 on the periodic table. Atomic mass of Fl: 289.0000 u. Fl is in period 7, group 14. Melting point of Fl: 200.00 K.Density of Fl: 14.00 g/cm³.

Why Flerovium Matters

Flerovium in everyday life and industry

In Your Home

  • No commercial applications
  • Research element only
  • Studied at JINR Dubna

Industry Uses

IndustryMay behave like a noble gas due to relativistic effects

In Your Body

✗ Not essential

No biological role. Too unstable for study. Might not interact chemically like lead.

Safety: Flerovium is radioactive

Common Misconceptions

Wrong:Flerovium behaves like lead, as its position suggests.
Correct:Flerovium might behave more like a noble gas than lead due to extreme relativistic effects closing its outer shell.
Wrong:Relativistic effects are negligible for superheavy elements.
Correct:Relativistic effects significantly affect flerovium's chemistry, potentially making it chemically inert.
Wrong:Superheavy elements are made just for curiosity.
Correct:The island of stability theory motivated flerovium's creation—searching for longer-lived superheavy nuclei.
