Traces of Francium are found in Uranium. Francium can be created simply by bombarding Thorium with protons. Out of all the unstable elements francium is the most unstable of the first 101 elements. There are only 20 to 30 grams of francium in our crust with only 20 known isotopes. Discovery: First scientist to claim the discovery was D.K. Dobroserdov but he later stopped the pursue of the element to begin teaching at the polyatomic institute of Odessa. Marguerite Perey claimed that he was the soul discoverer of the element francium in 1939 in Paris. Perey found it when she //a// decay product from actinium or 22387Fr. There were many claims of discovery twards the element many different variations of the elements have been found
