Vanadium Iodide

Vanadium is a Block D, Group 5, Period 4 element. The number of electrons in each of Vanadium's shells is 2, 8, 11, 2 and its electronic configuration is [Ar] 3d³ 4s². In its elemental form vanadium's CAS number is 7440-62-2. The vanadium atom has a radius of 131.1.pm and it's Van der Waals radius is 200.pm. Several vanadium compounds are toxic to some creatures despite the fact that it is an essential trace element. Vanadium is highly resistant to corrosion, so it is commonly used to alloy stainless steel grades. Vanadium compounds are used in advanced ceramics. Vanadium is a petrochemical cracking catalyst. Vanadium is available as metal and compounds with purities from 99% to 99.999% (ACS grade to ultra-high purity); metals in the form of foil, sputtering target, and rod, and compounds as submicron and nanopowder. Vanadium information, including Technical Data, Safety Data and its high purity properties , research , applications and other useful facts are discussed here . Scientific facts such as the atomic structure, ionization energy , abundance on Earth , conductivity and thermal properties are included. Vanadium was first discovered in Mexico City by Andres Manuel del Rio, a Spanish born and European educated Mexican mineralogist, in 1801. In honor of its beautiful multi-colored compounds, Vanadium was named after the word "Vanadis" meaning goddess of beauty in Scandinavian mythology. See Vanadium research below.

Iodine is a Block P, Group 17, Period 5 element. The number of electrons in each of Iodine's shells is 2, 8, 18, 18, 7 and its electronic configuration is [Kr] 4d¹⁰ 5s² 5p⁵. In its elemental form iodine's CAS number is 7553-56-2. The iodine atom has a radius of 133.1.pm and it's Van der Waals radius is 198.pm. Iodine in large amounts is poisonous but in small doses is only slightly toxic. Iodine forms compounds with many elements, but is less active than the other halogens, which displace it from iodides. Iodine exhibits some metallic-like properties. It dissolves readily in chloroform, carbon tetrachloride, or carbon disulfide to form purple solutions. It is only slightly soluble in water. Iodine compounds are important in organic chemistry and very useful in medicine. Potassium iodide finds use in photography. The deep blue color with starch solution is characteristic of the free element.Iodine is available in compounds with purities from 99% to 99.999% (ACS grade to ultra-high purity).
