| Silver Hexafluoroarsenate(V) is generally immediately available in most volumes. High purity, submicron and nanopowder forms may be considered.American Elements produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia)and follows applicable ASTM testing standards.Typical and custom packaging is available. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement. Silver is a Block D, Group 11, Period 5 element. The number of electrons in each of Silver's shells is 2, 8, 18, 18, 1 and its electronic configuration is [Kr]4d10 5s1. In its elemental form silver's CAS number is 7440-22-4. The silver atom has a radius of 144.5.pm and it's Van der Waals radius is 144.pm. Silver is not toxic although most silver salts are poisonous. Silver has a brilliant white metallic luster. It is a little harder than gold and is very ductile and malleable, being exceeded only by gold and perhaps palladium. Pure silver has the highest electrical and thermal conductivity of all metals, and possesses the lowest contact resistance. It is stable in pure air and water, but tarnishes when exposed to ozone, hydrogen sulfide, or air containing sulfur. Silver nitrate has wide application in painting, xerography, chemical electroplating, in components for electric batteries and in medicine as catalyst. Silver chloride is another important compound, due to its ductility and malleability. The organic compounds of the element are used in the coating of several metals and in dynamite or other explosive bars. Metallic silver is used as a catalyst of several oxidation reactions such as those of ethanol and other alcohols. Silver 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. Silver was first discovered by Early Man. Silver was named after the Anglo-Saxon word "seolfor" or "siolfur" meaning 'silver'. See Silver research below.
Arsenic is a Block P, Group 15, Period 4 element. The number of electrons in each of Arsenic's shells is 2, 8, 18, 5 and its electronic configuration is [Ar] 3d10 4s2 4p3. In its elemental form arsenic's CAS number is 1327-53-3. The arsenic atom has a radius of 124.5.pm and it's Van der Waals radius is 185.pm. Arsenic in the organic form is not harmful but in the inorganic form it is extremely toxic even in very small amounts. Arsenic has numerous applications as a semiconductor and other electronic applications as Indium arsenide, silicon arsenide and tin arsenidea. Arsenic is finding increasing uses as a doping agent in solid-state devices such as transistors. Gallium arsenide is used as a laser material to convert electricity directly into coherent light. Arsenic is used in bronzing and for hardening and improving the sphericity of shot. Due to its toxicity, arsenic compounds are used in insecticides and wood preservation.Arsenic 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. Arsenic 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. See Arsenic research below. |
