Francium occurs in nature (in very, very small quantities) as a decay product of other radioactive materials. "Why" is kind of a pointless question: it just is. it is extremely ephemeral. The longest half-life of any isotope of Francium is 22 minutes.
Nothing is made from francium.
As francium is a chemical element, it is made up of protons, neutrons and electrons.
Francium has any use.
Francium hasn't applications.
Francium was discovered by Marguerite Perey in 1939.
Natural francium is the decay product of actinium-227. Francium can be also obtained by nuclear reactions.
The most metallic element on the planet is Francium. It is the last element to be discovered that was not made synthetically.
The density of francium hydroxide was not estimated; an approximate estimation can be made by comparison with the alkali metals hydroxides.
Possibly, though francium is too rare and its half-life too short for it to have any practical uses, there may have been a Francium Bomb tested in the Pacific.
Francium was named after France, the country it was dicovered in.
Not known today but probably francium don't burn.
Francium has not applications and the oxide cannot be prepared.
