101Md Mendelevium

Year Discovered


Discovered By

Albert Ghiorso, Bernard Harvey, Gregory Choppen, Stanley Thompson and Glenn Seaborg of the USA

Biological Rating

Not necessary for life.


Named after Russian chemist Dimitri Mendeleev (who invented the Periodic Table), mendelevium is a highly radioactive metal. It has never been found naturally and only a few micrograms have been produced in laboratories. Its chemistry and appearance are not known with any certainty but should be similar to the other actinides. Mendelevium is too rare to have any commercial or industrial application. The most stable isotope of mendelevium has a half-life of 52 days.

Biological Benefits

Mendelevium has no biological use.

Role in Life Processes

No known benefit to life processes in plants and animals.


Mendelevium was first obtained by particle bombardment of einsteinium. Other methods of creating it are currently known.
