Magnesium is a Block S, Group 2, Period 3 element. The number of electrons in each of Magnesium's shells is 2, 8, 2 and its electronic configuration is [Ne] 3s2. In its elemental form magnesium's CAS number is 7439-95-4. The magnesium atom has a radius of 159.9.pm and it's Van der Waals radius is 173.pm. Magnesium the eighth most abundant element in the earth's crust. It is one third lighter than aluminum, and because of this is used in alloys that are essential for aerospace, satellite and missile construction. The metal improves the mechanical, fabrication, and welding characteristics of aluminum when used as an alloying agent. Uses also include flares and pyrotechnics due to its pyrophoric properties. Magnesium compounds, primarily magnesium oxide, are used mainly as refractory material in furnace linings for producing iron and steel, nonferrous metals, glass, and cement. High purity magnesium is found in dietary supplements. Magnesium was first discovered by Sir Humphrey Davy in 1808. The name Magnesium originates from a Greek district in Thessaly called Magnesia. See Magnesium research below.Magnesium the eighth most abundant element in the earth's crust.

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.
