where is astatine found in nature
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 Earthâs rarest element (only one ounce is contained within the entire planetâs crust). Astatine has been confirmed to behave chemically similar to that of other halogens, including iodine.
