* Atomic symbol: Fm
* Atomic number: 100
* Atomic mass: (most stable isotope) 257.095(1) u
* Electron configuration: [Rn] 5f12 7s2
* Oxidation states: +2, +3
* Discovery: Fermium was discovered in 1952 by a team of scientists led by Albert Ghiorso at the University of California, Berkeley. It was the first element beyond thorium (atomic number 90) to be synthesized.
* Name origin: Fermium is named after Enrico Fermi, the Italian-American physicist who made significant contributions to theoretical and experimental nuclear physics.
* Synthesis: Fermium is synthesized by bombarding uranium-238 with neutrons. The resulting isotope, fermium-257, has a half-life of about 100 days.
* Radioactivity: Fermium is highly radioactive. All isotopes of fermium are alpha emitters.
* Chemical properties: Fermium's chemical properties are not well known due to the scarcity and instability of its isotopes. However, it is predicted to be a soft, silvery-white metal with a high density.
* Applications: Due to its extremely low production rate and high radioactivity, fermium has no practical applications. It is mainly used for scientific research and experimentation.
