Francium is very rare and is only found in uranium minerals. When it is found, there is usually only one atom of it. It can be man made by bombarding thorium with protons. Francium is the most unstable of the first 101 elements. Natural Francium has never been isolated and is very radioactive. If it ever was isolated it would quickly decompose to other elements. Scientists have never been able to weigh any quanity of Francium.
