Wissenschaftliche Fakten, wie die atomare Struktur, Ionisierungenergie, Fülle auf der Erde, Leitfähigkeit und thermischen Eigenschaften sind im Preis inbegriffen.

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 compo nents 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 ist als Metall und Verbindungen mit Reinheiten von 99% auf 99,999% (ACS Note in höchster Reinheit); Metalle in Form von Folien, Sputtern Ziel, und Stab, und Verbindungen, wie Submikron- und Nanopuder-Verarbeitung.   Silver is also used in various metal alloys (See AE Alloys).
