What is Fermium as on the Periodic Table? Definition of the Fermium Element
A radioactive metallic element artificially produced, as by bombardment of plutonium with neutrons. Fermium does not exist naturally on Earth today but it has occurred in the past, produced in natural reactor deposits. The Atomic Number of this element is 100 and the Element Symbol is Fm.

What is Fermium? Origin / Meaning of the name Fermium
Named in honour of Enrico Fermi, Professor of Theoretical Physics at the University of Rome and Nobel Prize winner whose work resulted in the discovery of slow neutrons leading to the discovery of nuclear fission and the production of elements lying beyond what was until 1938 the Periodic Table.

Facts about the Discovery and History of the Fermium Element
Fermium was co-discovered by Albert Ghiorso and Glenn Seaborg in the USA in 1952.

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.

An invaluable source of facts and information as a Chemistry reference guide.

What is Fermium - IUPAC and the Modern Standardised Periodic Table
The Standardised Periodic Table in use today was agreed by the International Union of Pure Applied Chemistry, IUPAC, in 1985 and now recognises more periods and elements than Dimitri  Mendeleev knew in his day in his day but still all fitting into his concept of  the "Periodic Table" in which Fermium is just one element that can be found.
