Mendelevium Element Cube - 2" Acrylic Display - Atomic Number 101Mendelevium is a synthetic element with the symbol Md (formerly Mv) and atomic number 101. It can only be produced in particle accelerators by bombarding lighter elements with charged particles. All known isotopes of mendelevium have relatively short half lives; there are currently no uses for it outside basic scientific research, and only small amounts are produced. Mendelevium was discovered by bombarding einsteinium with alpha particles in 1955,
