The metallic radioactive transuranic element with atomic number 101 in the actinide series, discovered in 1955, is called Mendelevium. It is named after Dmitri Mendeleev, the Russian chemist who is best known for creating the periodic table of elements. It does not occur naturally and is only produced artificially in nuclear reactors or particle accelerators. It was first synthesized and discovered in 1955 by a team of scientists led by Albert Ghiorso at the University of California, Berkeley, USA.
