Symbol: At; atomic number: 85. See more. The halogen group in the Periodic Table consists of five chemically-related elements: fluorine, chlorine, bromine, iodine, and astatine (Table 3.8) and the halogen group is the only group that contains elements in three of the main states of matter (gas, liquid, solid) and standard temperature, and pressure (STP, 0 °C, 32 °F, 273.15 K and an absolute pressure of exactly 14.7 psi, 10 5 Pa Astatine is a chemical element with the symbol At and atomic number 85. It is the rarest naturally occurring element in the Earth’s crust, occurring only as of the decay product of various heavier elements. It is a radioactive element and is said to be the most heavier among the halogens. Astatine (At) may be the rarest naturally occurring element in the Earth’s crust, but it is a member of the halogen family [fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At)] and is presumed to have characteristics similar to other Group 17 elements. Astatine is the heaviest of the halogens and is essentially unavailable in nature with less than one teaspoon of the element found in the Earth’s crust at any one time.

Astatine, with an estimated total mass of 25 grams on Earth, is the rarest natural element here. It is produced in some decay chains, its most stable isotope has a half-life of only a little above eight hours. Chemically, astatine is similar to iodine, but more metallic and inert than this. Despite its rarity and short life, it has an application.
