Facts about the Definition of the Element Astatine
The Element Astatine is defined as...
A highly unstable radioactive element, the heaviest of the halogen series, that resembles iodine in solution.
Interesting Facts about the Origin and Meaning of the element name Astatine
What are the origins of the word Astatine ?
The name originates from the Greek word 'astatos' meaning unstable.
Facts about the Classification of the Element Astatine
Astatine is classified as an element in the 'Halogens' section which can be located in group 7 of the Periodic Table. The term "halogen" means "salt-former" and compounds containing halogens are called "salts". The halogens exist, at room temperature, in all three states of matter - Gases such as Fluorine & Chlorine, Solids such as Iodine and Astatine and Liquid as in Bromine.
Brief Facts about the Discovery and History of the Element Astatine
Astatine was discovered in University of California, Berkeley, USA by Dale R. Corson, K. R. MacKenzie, and Emilio Segre in 1940.
Occurrence of the element Astatine in the Atmosphere
The total amount of astatine in Earth's crust is estimated to be less than 1 oz (28 g) at any one time
Common Uses of Astatine
None. Astatine is studied by nuclear scientists. Its high radioactivity requires special handling techniques and precautions. Its toxicity is similar to that of iodine.

Facts and Info about the element Astatine - 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 which includes the Astatine element. The famous Russian Scientist, Dimitri Mendeleev, perceived the correct classification method of "the periodic table" for the 65 elements which were known in his time. The Standardised Periodic Table now recognises more periods and elements than Dimitri Mendeleev knew in his day but still all fitting into his concept of the "Periodic Table" in which Astatine is just one element that can be found.
