Mendelevium was discovered by Albert Ghiorso, Bernard G. Harvey, Gregory R. Choppin, Stanley G. Thompson, and Glenn T. Seaborg (US) in 1955. Named in honour of Dimitri Mendelejev, the Russian chemist who devised the periodic table. It is a synthetic radioactive metal. With extremely limited amounts of Mendelevium ever being synthesized it does not have any uses outside of scientific research capacities, so don't expect to find it powering a nuclear electric wheelchair or mobility scooter anytime soon. Mendelevium was made by bombarding einsteinium with helium ions.
