Did You Know?
It is the second rarest element in nature, after astatine. It is estimated that there are only about 20-30 grams of it in the entire Earth's crust at any time.
It is the most unstable of the first 101 elements; its most stable isotope has a half-life of only 22 minutes.
It was the last naturally occurring element to be discovered, identified in 1939 by Marguerite Perey in Paris. She named it after her home country, France.
As an alkali metal, it is predicted to be the most reactive metal on the periodic table, though it's too unstable to ever gather enough to test this.
It has no commercial applications and is only used for scientific research.
