Astatine is known to react with its lighter homologs iodine, bromine, and chlorine in the vapor state; these reactions produce diatomic interhalogen compounds with formulas AtI, AtBr, and AtCl.[55] The first two compounds may also be produced in water – astatine reacts with iodine/iodide so...

Astatine (At) is the heaviest element in the halogen group, and is highly radioactive, as its name (Greek for unstable) implies. The atomic number of astatine is 85, the atomic weight is approximately 210, the boiling point is 30°C and the melting point is 337°C. Astatine is rare ...
A highly unstable radioactive element, the heaviest of the halogen group, that resembles iodine in solution. Its longest lived isotope has a mass number of 210 and has a half-life of 8.3 hours. Atomic number 85; melting point 302°C; boiling point 337°C; valence probably 1, 3, 5, 7...
Physical and chemical properties The properties of astatine are not well known. The element breaks down too fast to allow experiments that take more than a few hours. No melting point, boiling point, or density is specified for astatine. The most complete experiments on astatine were begun in ...
