Silver Facts You May Not Know
Thursday, June 12th, 2008Silver is traded on world spot markets as well as on commodity futures exchanges. Industrial demand for silver is high which is one reason that the price of silver tracks the ups and downs of the world economy more so than gold. Another reason that silver is more responsive than gold to recessionary influences is that central banks do not trade in and accumulate silver as they do gold.
Silver is one of the few exceptions to the general order of filling of electron orbitals like copper directly above it in the Periodic Table. It fills all ten 4d states before it fills the second 5s state. You may not use silver yourself, but there’s an active worldwide market for it. Silver is less expensive than gold, and has equal or better optical properties.
Silver is a metallic element that is mined as a precious metal. It has various industrial uses, for example, in jewelry, silverware, electronic equipment, dental fillings, photographic processing, and disinfecting water. Silver is almost always monovalent in its compounds, but an oxide, a fluoride, and a sulfide of divalent silver are known. It does not oxidize in air but reacts with the hydrogen sulfide present in the air, forming silver sulfide (tarnish). Silver is available in different levels of purity. Fine silver is 99.9 percent silver; sterling silver is 92.5 percent silver, with other metals, typically copper, making up the difference, and coin silver is 90 percent silver with 10 percent copper.
