The Element Einsteinium


"The Atom"

What is Einsteinium as on the Periodic Table? Definition of the Einsteinium Element
A synthetic transuranic element first produced by neutron irradiation of uranium in a thermonuclear explosion and now usually produced in the laboratory by irradiating plutonium and other elements. It is attacked by Oxygen, steam and acids but not by alkalis.

Einsteinium is metallic and radioactive. 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 99 and the Element Symbol is Es.

What is Einsteinium? Origin / Meaning of the name Einsteinium
Named in honour of Albert Einstein, the famous physicist who proposed the theory of relativity.

What is Einsteinium? Periodic Table Group and Classification of the Einsteinium Element
Elements can be classified based on their physical states (States of Matter) e.g. gas, solid or liquid. This element is a solid. Einsteinium 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.

Facts about the Discovery and History of the Einsteinium Element
Einsteinium was first identified in 1952 by Albert Ghiorso at the University of California, Berkeley and another team headed by G.R. Choppin at Los Alamos National Laboratory, USA. Einsteinium was found in the debris of thermonuclear weapons 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.
