Web25 aug. 2024 · Astatine (atomic number 85, symbol At) is a radioactive metal, first produced by Emilio Segre , Kenneth Ross MacKenzie , and Dale Corson in 1940. In nature, it is formed by radioactive decay and exists in small amounts because of its short half-life. WebThe heaviest halogen is astatine (At), which is continuously produced by natural radioactive decay. All its isotopes are highly radioactive, and the most stable has a half-life of only about 8 h. Consequently, astatine is the least abundant naturally occurring element on Earth, with less than 30 g estimated to be present in Earth’s crust at any one time.
