Skip to site menu on this page Periodic Table of Elements Element Astatine - AtĬomprehensive data on the chemical element Astatine is provided on this page including scores of properties, element names in many languages, most known nuclides of Astatine.It can also cause severe radiation poisoning, which can lead to death. Astatine is very radioactive and emits high levels of radiation.It produced artificially in nuclear reactors and also produce particle accelerators. It is a highly radioactive element that not found in nature.Astatine is mainly used in research and in the production of radioactive tracers. However, it can be toxic if it enters the body in high doses. Astatine has no known biological role and not considered to be a major health threat.The most stable isotope, astatine-210, has a half-life of 8.1 hours.However it is the rarest naturally occurring element on Earth, occurring only in trace amounts. Astatine is a radioactive, synthetic element with the symbol At and atomic number 85.It quickly combines with other elements to form compounds. Therefore this electron easily lost, which makes astatine very reactive. Astatine has a relatively simple structure, with a single electron in its outermost shell.Astatine is a member of the halogen family, and has the chemical symbol At. It has a very short half-life, and therefore not found in nature in its elemental form. Astatine is a rare, unstable, radioactive element that found in the environment only in trace amounts.
