Can you make francium?
Since there is so little naturally occurring francium on earth, scientists must produce francium in order to study it. Francium can be produced by bombarding thorium with protons or by bombarding radium with neutrons. Francium’s most stable isotope, francium-223, has a half-life of about 22 minutes.
How do you make francium?
Francium can be produced by bombarding thorium with protons or by bombarding radium with neutrons. Francium’s most stable isotope, francium-223, has a half-life of about 22 minutes. It decays into radium-223 through beta decay or into astatine-219 through alpha decay.

Where is francium used?
Francium has been used in the field of research, chemistry and also in the atomic structure. It is used for diagnostics for curing cancers. It is also used in many spectroscopic experiments. Francium is a highly radioactive metal, and since it exhibits a short half-life, it does not have more impact on the environment.
