Flerovium was synthesized at JINR Dubna in 1999 by bombarding plutonium-244 with calcium-48. It is named after the Flerov Laboratory of Nuclear Reactions and physicist Georgy Flerov.
Flerovium-288
Half-life: About 0.65 seconds. Short-lived isotope used in superheavy decay-chain work.Flerovium-289
Half-life: About 2 seconds. Longest-lived commonly cited flerovium isotope; reported values vary slightly by source.- Research on superheavy nuclei near the island of stability
- Gas-phase chemistry testing volatile Group 14 behavior
- Relativistic chemistry studies comparing flerovium with lead and copernicium
Flerovium has no biological role. It is synthetic, radioactive and produced only in atom-scale quantities.
- Element 114 has long been connected with the predicted island of stability, especially for neutron-rich isotopes not yet reached.
- Flerovium appears much more volatile than a simple lead-like Group 14 trend would predict.
- Its chemistry is a key test of how relativistic effects reshape the end of the periodic table.
- Flerovium has atomic number 114 and symbol Fl.
- Its predicted electron configuration is [Rn] 5f¹⁴ 6d¹⁰ 7s² 7p².
- Flerovium is Group 14 below lead, but its chemistry may be unusually volatile.
- Remember Fl for island of stability discussions around Z = 114.
What is the atomic number of flerovium?
The atomic number of flerovium is 114.
What is the electron configuration of flerovium?
Flerovium is commonly listed with the predicted electron configuration [Rn] 5f¹⁴ 6d¹⁰ 7s² 7p².
What is flerovium used for?
Flerovium is used only in superheavy element nuclear and theoretical chemistry research.
Why is flerovium linked to the island of stability?
Atomic number 114 is near a predicted proton shell closure, so neutron-rich flerovium isotopes are important in island-of-stability models.
Who is flerovium named after?
Flerovium is named after the Flerov Laboratory of Nuclear Reactions, which honors Georgy Flerov.
