Tarix
Mendelevium was discovered by Albert Ghiorso, Glenn T. Seaborg, Gregory R. Choppin, Bernard G. Harvey and Stanley G. Thompson in 1955 at the University of California, Berkeley.
It was produced by the bombardment of einsteinium with helium.
Mendelevium was identified by chemical analysis in an ion exchange experiment.
