Overview. Astatine is a member of the halogen family, elements in Group 17 (VIIA) of the periodic table. It is one of the rarest elements in the universe. Scientists believe that no more than 25 grams exist on the Earth's surface.statine is far too rare to have any uses. Some research suggests a possible medical use, however. Astatine is similar to the elements above it in Group 17 (VIIA) of the periodic table, especially iodine.
Although astatine is produced by radioactive decay in nature, it is typically found only in miniscule amounts due to its short half-life (the time it takes for one half of the atoms of a given radioactive substance to decay or disintegrate). Trace amounts are also found in natural minerals. Astatine is currently Earthâs rarest element (only one ounce is contained within the entire planetâs crust). Astatine has been confirmed to behave chemically similar to that of other halogens, including iodine.
