See more Gadolinium products. Gadolinium (atomic symbol: Gd, atomic number: 64) is a Block F, Group 3, Period 6 element with an atomic radius of 157.25. Gadolinium Bohr ModelThe number of electrons in each of Gadolinium's shells is [2, 8, 18, 25, 9, 2] and its electron configuration is [Xe] 4f7 5d1 6s2. The gadolinium atom has a radius of 180 pm and a Van der Waals radius of 237 pm. Gadolinium was discovered by Jean Charles Galissard de Marignac in 1880 and first isolated by Lecoq de Boisbaudran in 1886. In its elemental form, gadolinium has a silvery-white appearance. Gadolinium is a rare earth or lanthanide element that possesses unique properties advantageous to specialized applications such as semiconductor fabrication and nuclear reactor shielding. Elemental Gadolinium PictureIt is utilized for both its high magnetic moment (7.94μ B) and in phosphors and scintillator crystals. When complexed with EDTA ligands, it is used as an injectable contrast agent for MRIs. The element is named after the Finnish chemist and geologist Johan Gadolin.

See more Germanium products. Germanium (atomic symbol: Ge, atomic number: 32) is a Block P, Group 14, Period 4 element with an atomic weight of 72.63. Germanium Bohr ModelThe number of electrons in each of germanium's shells is 2, 8, 18, 4 and its electron configuration is [Ar] 3d10 4s2 4p2. The germanium atom has a radius of 122.5 pm and a Van der Waals radius of 211 pm. Germanium was first discovered by Clemens Winkler in 1886. In its elemental form, germanium is a brittle grayish white semi-metallic element. Germanium is too reactive to be found naturally on Earth in its native state. High Purity (99.999%) Germanium (Ge) MetalIt is commercially obtained from zinc ores and certain coals. It is also found in argyrodite and germanite. It is used extensively as a semiconductor in transitors, solar cells, and optical materials. Other applications include acting an alloying agent, as a phosphor in fluorescent lamps, and as a catalyst. The name Germanium originates from the Latin word "Germania" meaning "Germany," For more information on germanium, including properties, safety data, research, and American Elements' catalog of germanium products, visit the Germanium element page.

See more Silicon products. Silicon (atomic symbol: Si, atomic number: 14) is a Block P, Group 14, Period 3 element with an atomic weight of 28.085. Silicon Bohr MoleculeThe number of electrons in each of Silicon's shells is 2, 8, 4 and its electron configuration is [Ne] 3s2 3p2. The silicon atom has a radius of 111 pm and a Van der Waals radius of 210 pm. Silicon was discovered and first isolated by Jöns Jacob Berzelius in 1823. Silicon makes up 25.7% of the earth's crust, by weight, and is the second most abundant element, exceeded only by oxygen. The metalloid is rarely found in pure crystal form and is usually produced from the iron-silicon alloy ferrosilicon. Elemental SiliconSilica (or silicon dioxide), as sand, is a principal ingredient of glass, one of the most inexpensive of materials with excellent mechanical, optical, thermal, and electrical properties. Ultra high purity silicon can be doped with boron, gallium, phosphorus, or arsenic to produce silicon for use in transistors, solar cells, rectifiers, and other solid-state devices which are used extensively in the electronics industry.The name Silicon originates from the Latin word silex which means flint or hard stone.
