What's in a name? Named in honor of the Flerov Laboratory of Nuclear Reactions.

Say what? Flerovium is pronounced as flee-ROVE-ee-em.

History and Uses:

Flerovium was first produced by scientists working at the Joint Institute for Nuclear Research in Dubna, Russia in 1998. They bombarded atoms of plutonium with ions of calcium. This produced a single atom of flerovium-289, an isotope with a half-life of about 21 seconds.

Flerovium's most stable isotope, flerovium-289, has a half-life of about 0.97 seconds. It decays into copernicium-285 through alpha decay.

Since only a few atoms of flerovium have ever been produced, it currently has no uses outside of basic scientific research.
