1. Fermium

   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. A total of 19 isotopes are known, with 257Fm being the longest-lived with a half-life of 100.5 days. 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. Its chemistry is typical for the late actinides, with a preponderance of the +3 oxidation state but also an accessible +2 oxidation state. 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.

1. fermium

   Fermium is a synthetic, radioactive metallic element with the symbol Fm and atomic number 100. It was discovered in 1952 in the debris of the first hydrogen bomb explosion and is named after physicist Enrico Fermi. Due to its large mass and radioactivity, it is not used commercially. Fermium is one of the heaviest elements on the periodic table and does not occur naturally in the environment. It is primarily used for scientific research purposes.
