Silver

Silver is a chemical element; it has symbol Ag (from Latin argentum 'silver') and atomic number 47. A soft, whitish-gray, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. Silver is found in the Earth's crust in the pure, free elemental form ("native silver"), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Most silver is produced as a byproduct of copper, gold, lead, and zinc refining. Silver has long been valued as a precious metal, commonly sold and marketed beside gold and platinum. Silver metal is used in many bullion coins, sometimes alongside gold: while it is more abundant than gold, it is much less abundant as a native metal. Its purity is typically measured on a per-mille basis; a 94%-pure alloy is described as "0.940 fine". As one of the seven metals of antiquity, silver has had an enduring role in most human cultures. In terms of scarcity, silver is the most abundant of the big three precious metals, platinum, gold, and silver; among these, platinum is the rarest, with around 139 troy ounces of silver mined for every one of platinum. Other than in currency and as an investment medium (coins and bullion), silver is used in solar panels, water filtration, jewellery, ornaments, high-value tableware and utensils (hence the term "silverware"), in electrical contacts and conductors, in specialised mirrors, window coatings, in catalysis of chemical reactions, as a colorant in stained glass, and in specialised confectionery. Its compounds are used in photographic and X-ray film. Dilute solutions of silver nitrate and other silver compounds are used as disinfectants and microbiocides (oligodynamic effect), added to bandages, wound-dressings, catheters, and other medical instruments.

Most silver is produced as a byproduct of copper, gold, lead, and zinc refining "Refining (metallurgy)"). [...] Silver has a brilliant, white, metallic luster that can take a high polish, and which is so characteristic that the name of the metal itself has become a color name "Silver (color)"). Protected silver has greater optical reflectivity than aluminium at all wavelengths longer than ~450 nm. At wavelengths shorter than 450 nm, silver's reflectivity is inferior to that of aluminium and drops to zero near 310 nm. [...] ## History Silver was known in prehistoric times: the three metals of group 11, copper, silver, and gold, occur in the elemental form in nature and were probably used as the first primitive forms of money as opposed to simple bartering. Unlike copper, silver did not lead to the growth of metallurgy, on account of its low structural strength; it was more often used ornamentally or as money. Since silver is more reactive than gold, supplies of native silver were much more limited than those of gold. For example, silver was more expensive than gold in Egypt until around the fifteenth century BC: the Egyptians are thought to have separated gold from silver by heating the metals with salt, and then reducing the silver chloride produced to the metal.

• Silver | Facts, Properties, & Uses

  Together with gold and the platinum-group metals, silver is one of the so-called precious metals. Because of its comparative scarcity, brilliant white color, malleability, ductility, and resistance to atmospheric oxidation, silver has long been used in the manufacture of coins, ornaments, and jewelry. Silver has the highest known electrical and thermal conductivity of all metals and is used in fabricating printed electrical circuits and as a vapor-deposited coating for electronic conductors; it is also alloyed with such elements as nickel or palladium for use in electrical contacts. Silver also finds use as a catalyst for its unique ability to convert ethylene to ethylene oxide, which is a precursor of many organic compounds. Silver is one of the noblest—that is, least chemically [...] silver (Ag), chemical element, a white lustrous metal valued for its decorative beauty and electrical conductivity. Silver is located in Group 11 (Ib) and Period 5 of the periodic table, between copper (Period 4) and gold (Period 6), and its physical and chemical properties are intermediate between those two metals.

• Buy High-Purity Silver Metal | Ag ≤ 99.999% (5N)

  Silver (Ag) is a soft, white, lustrous transition metal known for its exceptional electrical and thermal conductivity—higher than any other element. It has a melting point of 961.78 °C and is highly ductile and malleable. Though it tarnishes upon exposure to air due to surface oxidation, Silver remains chemically stable in many laboratory and industrial environments. It is typically extracted from ores like argentite and refined through processes such as smelting or electrolysis.

• SILVER ESSENTIALS

  Silver is also one of the world’s best conductors of electricity, allowing its use in electronic components such as wires, switches and printed circuit boards. The combination of ductility and electrical conductivity makes silver perfect for microelectronics devices such as smartphones, where it can be bent and squeezed into tiny spaces without breaking. Silver also exhibits the singular property of penetrating bacteria cell walls – while not harming mammalian cells – and destroying the ability of the microbe to reproduce. This allows silver ions to be employed as a biocide, which is growing increasingly important as overuse of chemical antibiotics is causing some bacteria to become immune. [...] Select Page ### The Indispensable Element Every element is unique in its own way, but silver’s characteristics make it exceptional among all those found in the Periodic Table. For example, silver is malleable and ductile, making if perfect for jewelry and silverware. Because it is one of the world’s most reflective substances, silver has an exquisite shine. In fact, silver’s atomic symbol is Ag, from the Latin argentum, taken from the Greek ὰργὀς meaning ‘shiny.’ [...] As if this isn’t enough, silver has been prized for centuries as an investment and storehouse of wealth and used as a medium of exchange in much the way that gold has been used. However, because of its lower value, silver is more available to a greater number of people who choose to keep physical silver instead of paper currency. #### Where does silver come from? Silver is found in the earth’s crust on its own in a pure form known as ‘native silver.’ More commonly, it is a mined as a secondary metal mainly found combined with gold, copper and lead, from which it must be separated.

• Silver - Element information, properties and uses

  Silver is used to make mirrors, as it is the best reflector of visible light known, although it does tarnish with time. It is also used in dental alloys, solder and brazing alloys, electrical contacts and batteries. Silver paints are used for making printed circuits. Silver bromide and iodide were important in the history of photography, because of their sensitivity to light. Even with the rise of digital photography, silver salts are still important in producing high-quality images and protecting against illegal copying. Light-sensitive glass (such as photochromic lenses) works on similar principles. It darkens in bright sunlight and becomes transparent in low sunlight. [...] the basis for the economies of some ancient Mediterranean civilizations. It's a soft and pliable metal with a relatively low melting point and that means it can be hammered and moulded into shape, so the same metal that was used to make money that was gradually outdated could also be transformed into vases, platters, cutlery and goblets; tableware that has created displays of household wealth through the centuries. But a gleaming collection of silverware isn't easy to maintain. The metal reacts with sulphur in the air, rapidly forming a dull, dark silver sulphide tarnish that has to be polished off. So it's a high maintenance element; another reason why it has always been outshone by gold. But the same chemical properties that tarnished its image let it to make another mark in history, by [...] Biological role The role of the element in humans, animals and plants. Natural abundance Where the element is most commonly found in nature, and how it is sourced commercially. ## Uses and properties ## Uses and properties Image explanation The symbol is based on the widely used alchemical symbol for silver. In the background is a detail from the ‘Gundestrup Cauldron’, the largest known example of European Iron Age silver work. Appearance Silver is a relatively soft, shiny metal. It tarnishes slowly in air as sulfur compounds react with the surface forming black silver sulfide. Uses Sterling silver contains 92.5% silver. The rest is copper or some other metal. It is used for jewellery and silver tableware, where appearance is important.
