What is francium used for?
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.
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.
