Astatine monoiodide Astatine monoiodide is an interhalogen compound with the chemical formula AtI. It is the 2nd heaviest known interhalogen compound (with the possible exception of iodine pentabromide, IBr5, whose existence is disputed, else 3rd). Astatine monoiodide is produced by the direct combination of astatine and iodine in a 1:1 molar ratio: 2 At + I2 → 2 AtI. Astatine monoiodide is an interhalogen compound with the chemical formula At I. It is the heaviest known interhalogen compound (with the possible exception of iodine pentabromide, IBr5, whose existence is disputed). Production[edit]. The covalent bond between the two atoms has some character, the less electronegative halogen, X, being oxidised. All combinations of fluorine, chlorine, bromine, and iodine that have the general formula are known. Astatine monoiodide ( AtI ) is made by direct combination of astatine Aluminium. + 2 Al A stable derivative of aluminium monoiodide is the cyclic adduct formed with triethylamine , Al4I4 ( Thallium(I) iodide.

Infobox references. Astatine monoiodide is an interhalogen compound with the chemical formula At I. It is the heaviest known interhalogen compound (with the possible exception of iodine pentabromide, IBr5, whose existence is disputed). Production. Astatine is a chemical element. Its atomic number (which is the number of protons in it) is 85, and its atomic weight (which is approximately the number of protons plus the number of neutrons in it) is 210. It is part of the Group 7 (halogens) on the periodic table of elements. Some of its isotopes may be in nature. But because it is extremely unstable (roughly speaking, the atoms fall apart), only about an ounce exists in the Earth's crust at one point in time. It is radioactive.
