What is Mendelevium as on the Periodic Table? Definition of the Mendelevium Element A radioactive transuranic element synthesized by bombarding einsteinium with alpha particles. Mendelevium is the first transferium element. A transuranic element means an element with atoms heavier than those of Uranium with an atomic number greater than 92. The Atomic Number of this element is 101 and the Element Symbol is Md. The original chemical symbol proposed was My but this was changed in 1955. What is Mendelevium? Origin / Meaning of the name Mendelevium Named in honour of Dmitri Mendeleev who developed the Periodic Table of the chemical elements. Facts about the Discovery and History of the Mendelevium Element Mendelevium was first synthesized in the USA by Albert Ghiorso (team leader), Glenn T. Seaborg, Bernard Harvey, and Greg Choppin in 1955. Discovery credited to Glenn T. Seaborg. Glenn T. Seaborg The American scientist Glenn T. Seaborg (1912 - 1999) won the 1951 Nobel Prize in Chemistry for "discoveries in the chemistry of the transuranium elements". Glenn Seaborg contributed to the discovery and isolation of ten elements: plutonium, americium, curium, berkelium, californium, einsteinium, fermium, mendelevium, nobelium and element 106, which was named seaborgium in his honor whilst he was still living. Glenn Seaborg also developed the actinide concept, which led to the current arrangement of the actinoid series in the periodic table of the elements. Glenn Seaborg (1912 - 1999) What is Mendelevium?
