Rubidium Iodide

Rubidium is a Block S, Group 1, Period 5 element. The number of electrons in each of Rubidium's shells is 2, 8, 18, 8, 1 and its electronic configuration is [Kr] 5s¹. In its elemental form rubidium 's CAS number is 7440-17-7. The rubidium atom has a radius of 247.5.pm and it's Van der Waals radius is 200.pm. Rubidium is not toxic. Rubidium has various applications in medicine and in photoelectronics. Rubidium 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. It is used in photo and detection cells production. Rubidium glass compositions have the highest room temperature conductivity. It has been used as a "getter" in vacuum tubes. Rubidium was first discovered by Robert Wilhem Bunsen and Gustav Robert Kirchhoff in 1861. The name Rubidium, originates from the Latin word 'Rubidius' which means dark or deepest red.

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).
