Thallium is a Block P, Group 13, Period 6 element. The number of electrons in each of Thallium's shells is 2, 8, 18, 32, 18, 3 and its electronic configuration is [Xe] 4f14 5d10 6s2 6p1. In its elemental form thallium's CAS number is 7440-28-0. The thallium atom has a radius of 170.pm and it's Van der Waals radius is 196.pm. Thallium and its compounds are highly toxic. Thallium is primarily used for its electrical conductivity as thallium sulfide which changes with exposure to infrared light. This ability makes the compound useful in photocells. Thallium bromide-iodide crystals have been used as infrared optical materials. Thallium has been used, with sulfur or selenium and arsenic, to produce low melting glasses which becomes fluid between 125 and 150 C. These glasses have properties at room temperatures similar to ordinary glasses and are said to be durable and insoluble in water. Thallium oxide has been used to produce glasses with a high index of refraction, and is also used in the manufacture of photo cells. Thallium is available as metal and compounds with purities from 99% to 99.9999% (ACS grade to ultra-high purity); metals in the form of foil, sputtering target, and rod, and compounds as submicron and nanopowder. Thallium was first discovered by Sir William Crookes in 1861.
Chromium is a Block D, Group 6, Period 4 element. The number of electrons in each of Chromium's shells is 2, 8, 13, 1 and its electronic configuration is [Ar] 3d5 4s1. In its elemental form chromium's CAS number is 7440-47-3. The chromium atom has a radius of 124.9.pm and it's Van der Waals radius is 200.pm. Hexavalent chromium is toxic. Chromium is highly resistant to corrosion. This has led to its use in numerous alloying and steel producing applications. When chromium is added to glass or ceramic glazes, it produces a brilliant green. Chromium 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 also used as a paint pigment for this purpose.Although chromium metal is an essential trace element, hexavalent chromium (Cr(VI)) is especially toxic and carcinogenic. Recently, chromites have formed the basis for cathode compositions for oxygen generation and fuel cell applications. Chromium 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. Chromium was first discovered by Anders Ekeberg in 1802. Due to its various colorful compounds, Chromium was named after the Greek word 'chroma' meaning color. See Chromium research below.
