Im Periodensystem steht es in der 7. The percentage by weight of any atom or group of atoms in a compound can be computed by dividing the total weight of the atom (or group of atoms) in the formula by the formula weight and multiplying by 100.Formula weights are especially useful in determining the relative weights of reagents and products in a chemical reaction.
Temperatures greater than 750 °C are required for fluorine, chlorine, and bromine to dissociate to a similar extent.

For bulk stoichiometric calculations, we are usually determining molar mass, which may also be called standard atomic weight or average atomic mass.Using the chemical formula of the compound and the periodic table of elements, we can add up the atomic weights and calculate molecular weight of the substance.Calculate the molecular weight For physicochemical, thermodynamic, transport, spectra, and other property data & information, the followings are available from
; Brizel, H.E. ENDMEMO. of a chemical compoundMore information on The low solubility of Aqueous solutions of iodide salts dissolve iodine better than pure water. The exceptions are decidedly in the minority and stem in each case from one of three causes: extreme inertness and reluctance to participate in chemical reactions (the Given the large size of the iodide anion and iodine's weak oxidising power, high oxidation states are difficult to achieve in binary iodides, the maximum known being in the pentaiodides of Lower iodides may be produced either through thermal decomposition or disproportionation, or by reducing the higher iodide with hydrogen or a metal, for example:Most of the iodides of the pre-transition metals (groups 1, 2, and 3, along with the Hypoiodous acid is unstable to disproportionation.
Therefore 10 moles of iodine would be 1299g. der 17. Selectively accumulating in the thyroid gland, iodine I 131 emits beta and gamma particles, thereby killing thyroid cells and decreasing thyroid hormone production. Iodide anions may sometimes also be found combined with mercury, copper and lead, but minerals with such compositions are even more scarce.Except where otherwise noted, data are given for materials in their Mutations in this gene are associated with thyroid dyshormonogenesis 1. 133-135, IBSN 0-03-075176-4Holleman, A. F.; Wiberg, E. "Inorganic Chemistry" Academic Press: San Diego, 2001. I2 is a metallic gray solid at room temperature. Iodine conforms to the prevailing trend, being a shiny black crystalline solid that melts at 114 °C and boils at 183 °C to form a violet gas. Iodide, being large, is less hydrophilic compared to the smaller anions. The hypoiodite ions thus formed disproportionate immediately to give iodide and iodate:Iodous acid and iodite are even less stable and exist only as a fleeting intermediate in the oxidation of iodide to iodate, if at all.Many periodates are known, including not only the expected tetrahedral They are thermodymically and kinetically powerful oxidising agents, quickly oxidising MnWhen iodine dissolves in strong acids, such as fuming sulfuric acid, a bright blue The only important polyiodide anion in aqueous solution is linear Many other polyiodides may be found when solutions containing iodine and iodide crystallise, such as Organoiodine compounds have been fundamental in the development of organic synthesis, such as in the Some drawbacks of using organoiodine compounds as compared to organochlorine or organobromine compounds is the greater expense and toxicity of the iodine derivatives, since iodine is expensive and organoiodine compounds are stronger alkylating agents.Iodine is the least abundant of the stable halogens, comprising only 0.46 The caliche was the main source of iodine in the 19th century and continues to be important today, replacing These sources ensure that Chile and Japan are the largest producers of iodine today.About half of all produced iodine goes into various organoiodine compounds, another 15% remains as the pure element, another 15% is used to form The iodide and iodate anions are often used for quantitative volumetric analysis, for example in Cesium iodide and thallium-doped sodium iodide are used in crystal Elemental iodine is used as a disinfectant either as the element, or as the water-soluble The antimicrobial action of iodine is quick and works at low concentrations, and thus it is used in operating theatres.Inorganic iodides find specialised uses.

For other uses, see Desormes and Clément made their announcement at the Institut impérial de France on 29 November 1813; a summary of their announcement appeared in the Harper, P.V. There may be different names of the Iodine compound depending on the various situations of industrial applications, which are given below including the registry numbers if available:
