Francium

Element #87, with the symbol Fr. Francium is the exact opposite of stable, decaying in a matter of nanoseconds. Its most stable isotope, Francium-223, decays in only 22 minutes. It is extremely radioactive, and has no uses besides being a space-filler on the periodic table. One could say that it could be used as a weapon, but the fact that only 30 grams of the stuff can exist on Earth at a time would rule out that suggestion. Single Francium atoms are also fiendishly difficult to synthesize. These factors effectively make Francium forever useless and obsolete. Francium was named after France, where it was discovered in Paris.

Francium has the lifespan of an antivaxxer's child.

eka francium

a theoretical 119th element which is an alkali metal. In theory since it is lower down in the periodic table, it will be highly explosive

eka francium go brrrr

Francium Shake

A dodgy and illegal drink that mainly caused hallucinations. Created by mixing LSD, ketamine and pure alcohol, this deadly hallucinogenic beverage is often prepared with a magic mushroom on the edge of the glass.

"MATE! WHY ARE THERE 19 OF ME? AND WHY IS MY MOTHER SHOOTING ADOLF HITLER??? ARRRRRGH!"
"Boss.... You didn't drink that Francium Shake, did you? Boss... Why are you eating the bartender...?"

Francium

Francium is a chemical element; it has symbol Fr and atomic number 87. It is extremely radioactive; its most stable isotope, francium-223 (originally called actinium K after the natural decay chain in which it appears), has a half-life of only 22 minutes. It is the second-most electropositive element, behind only caesium, and is the second rarest naturally occurring element (after astatine). Francium's isotopes decay quickly into astatine, radium, and radon. The electronic structure of a francium atom is Rn 7s1; thus, the element is classed as an alkali metal.

Bulk francium has never been seen. Because of the general appearance of the other elements in its periodic table column, it is presumed that francium would appear as a highly reactive metal if enough could be collected together to be viewed as a bulk solid or liquid. Obtaining such a sample is highly improbable since the extreme heat of decay resulting from its short half-life would immediately vaporize any viewable quantity of the element.

Francium was discovered by Marguerite Perey in France (from which the element takes its name) in 1939. Before its discovery, francium was referred to as eka-caesium or ekacaesium because of its conjectured existence below caesium in the periodic table. It was the last element first discovered in nature, rather than by synthesis. Outside the laboratory, francium is extremely rare, with trace amounts found in uranium ores, where the isotope francium-223

francium will last a little time
