The Element Fermium


"The Atom"

What is Fermium? Periodic Table Group and Classification of the Fermium Element
Elements can be classified based on their physical states (States of Matter) e.g. gas, solid or liquid. This element is a solid. Fermium classified as an element in the Actinide series as one of the "Rare Earth Elements" which can located in Group 3 elements of the Periodic Table and in the 6th and 7th periods. The Rare Earth Elements are of the Lanthanide and Actinide series.

Most of the elements in the Actinide series are synthetic or man-made. Nearly 75% of all the elements in the Periodic Table are classified as metals which are detailed in the List of Metals.

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.
