Check the listing for details. Fermium Element Cube. Condition: New. Listed at 53.55 USD. Fermium Element Cube Made In USA 2x2x2 inches Radioactive symbol. No sample. Fermium is a synthetic element with the symbol Fm and atomic number 100. It is an actinide and the heaviest element that can be formed by neutron bombardment of lighter elements, and hence the last element that can be prepared in macroscopic quantities, although pure fermium metal has not yet been prepared. It was discovered in the debris of the first hydrogen bomb explosion in 1952, and named after Enrico Fermi, one of the pioneers of nuclear physics. Owing to the small amounts of produced fermium and all of its isotopes having relatively short half-lives, there are currently no uses for it outside basic scientific research. This display is contained within crystal clear lucite acrylic. Made In USA 2x2x2 inches Radioactive symbol. No sample. Fermium is a synthetic element with the symbol Fm and atomic number 100.
