Mendelevium is yet another product of the Bekeley lab at the University of California. It was discovered in 1955, named after Dmitri Mendeleyev, who devised the periodic table.

256Md was first produced by bombarding einsteinium-253 with helium nuclei (or alpha particles). Scientists identified mendelevium from the slightest shred of evidence as mendelevium is the first synthetic, or man-made, element that was assembled virtually one atom at a time. Little is known about the nature of mendelevium compounds.
