About Flerovium
Flerovium was produced by bombarding plutonium with calcium ions. Relativistic effects may make it volatile and noble-gas-like.
Uses & Applications
No practical applications. Scientific research only.
Fun Fact
Flerovium may be one of the most unusual elements -- despite being in lead's group, it might behave like a noble gas.
