About Mendelevium

Discovered in the labs of the University of California in the 1950s, Mendelevium is a radioactive chemical element named after Dmitri Mendeleev, a Russian scientist and the creator of the Periodic Table. It is one of the actinides and a toxic material which can be produced only in nuclear reactors as a result of bombarding einsteinium molecules. Mendelevium is considered to be a transuranic element and has no other purpose but scientific research. It is produced in micro amounts of a few grams a year.
