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.
Astatine is an extremely radioactive element; all its isotopes have short half-lives of 8.1 hours or less, decaying into bismuth, polonium, radon, or other astatine isotopes. Most of its isotopes are very unstable with half-lives of one second or less.our isotopes of astatine were subsequently found in nature, although it is the least abundant of all the naturally occurring elements, with much less than one gram being present at any given time in the Earth's crust.
