Never found in free form in nature. Used in water purification, bleaches, acids and many, many other compounds such as chlorofluorocarbons (CFC). Salt (sodium chloride, NaCl) is its most common compound. Commercial quantities are produced by electrolysis of aqueous sodium chloride (seawater or brine from salt mines). BXCfBl4rmh0 Chlorine

Ununquadium (Uuq) was the temporary IUPAC systematic element name.

In 1998, a team led by Yuri Oganessian and Vladimir Utyonkov at the Joint Institute for Nuclear Research, Dubna produced flerovium by bombarding plutonium with calcium.

In an experiment lasting 40 days, 5 x 10¹⁸ atoms of calcium to be fired at plutonium to produce a single atom of flerovium. Named after the founder of the Flerov Laboratory of Nuclear Reactions, the Soviet physicist Georgy Flyorov 17 1774 Carl William Scheele Sweden From the Greek word "chloros" meaning "pale green"

Flerovium is harmful due to its radioactivity

The longest-lived isotope currently known is ²⁸⁹Fl

Flerovium is used for scientific research purposes only.
