Francium (was) is used only for studies in research laboratories.
Francium hasn't practical uses.
As francium is the rarest type of atoms in the world, there is approximately only 20 francium atoms left on Earth.
Protactiniumand Francium have no known uses outside the lab. Protactinuium is an unwanted natural byproduct of uranium decay. Francium is radioactive and very unstable.
Not known, probably any odor
Uses of francium are limited to only scientific research.This is mostly because it is difficult to find or make and it has a very short half life (it decays quickly into other elements).Francium (and not fracium) is used only in specialized laboratories for reseach in chemistry in physics.With a half life of only 22 minutes, francium is not only completely useless, it is also not likely that anyone could gather enough of it together to do anything meaningfull with it.Francium has only some rare applications in research laboratories; see the link.Unfortunately, the uses for the radioactive element Francium are limited to only scientific research. This is mostly because it is difficult to find or make and it has a very short half life (it decays quickly).However this element is the one element that is the most reactive to water because it is the most reactive alkali metal, a family of metals that all react to water. This basically means if you drop a large sample of Francium into a tub of water it will explode.there is no known uses for francium.there is not much of Francium around, and what there is or is made does not last for long (disintegrates into lighter elements in a few hours). probably it is being investigated or used in some physics experiments somewhere and it seems unlikely to show up as a food additive at your grocery store anytime soon.

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 has not now practical applications; francium is used only for scientific studies.
