fermium
Synthetic radioactive metal
Fermium is a synthetic radioactive element, atomic number 100, created in nuclear reactors and particle accelerators.
Named after physicist Enrico Fermi, it belongs to the actinide series and has no practical applications outside scientific research.
Like other heavy transuranic elements, fermium exists only briefly before decaying.
