This page is about silver the chemical element. For the color, see silver (color). See also Silver (disambiguation) \nSilver is a chemical element with the symbol Ag (from the traditional abbreviation for the Latin argentum). A soft white lustrous transition metal, it has the highest electrical and thermal conductivity of any metal and occurs in minerals and in free form. This metal is used in coins, jewelry, tableware, photography, and in mirrors.\n\nContents [hide]\n1 Notable characteristics \n2 Applications \n3 History \n4 Occurrence \n5 Price \n6 Isotopes \n7 Silver in medicine \n7.1 Health precautions \n7.2 Alternative medicine \n8 References \n9 See also \n10 External links \n10.1 Publications on health effects \n \n\n\n[edit]\nNotable characteristics\n \nA chunk of silverSilver is a very ductile and malleable (slightly harder than gold) univalent coinage metal with a brilliant white metallic luster that can take a high degree of polish. It has the highest electrical conductivity of all metals, even higher than copper, but its greater cost and tarnishability has prevented it from being widely used in place of copper for electrical purposes.\n\nPure silver also has the highest thermal conductivity, whitest color, the highest optical reflectivity (although it is a poor reflector of ultraviolet light), and the lowest contact resistance of any metal. Silver halides are photosensitive and are remarkable for the effect of light upon them. This metal is stable in pure air and water, but does tarnish when it is exposed to ozone, hydrogen sulfide, or air with sulfur in it. The most common oxidation state of silver is +1 (for example, silver nitrate; AgNO3), a few +2 (for example, silver(II) fluoride; AgF2) and +3 compounds (for example, silver(III) persulfate; Ag2(SO5)3) are also known.\n\n[edit]\nApplications\nThe principal use of silver is as a precious metal. Its salts, especially silver nitrate and silver halides, are also widely used in photography (which is the largest single end use of silver). Some other uses for silver are as follows:\n\nElectrical and electronic products, which need silver's superior conductivity, even when tarnished. For example, printed circuits are made using silver paints, and computer keyboards use silver electrical contacts. Silver is also used in high voltage contacts because it is the only metal that will not arc across contacts, hence it is extremely safe. \nMirrors which need superior reflectivity for visible light are made with silver as the reflecting material in a process called silvering. Common mirrors are backed with aluminium. \nSilver has been coined to produce money since 700 BC by the Lydians, in the form of electrum. Later, silver was refined and coined in its pure form. The words for "silver" and "money" are the same in at least 14 languages. \nThe metal is chosen for its beauty in the manufacture of jewelry and silverware, which are traditionally made from the silver alloy known as Sterling silver, which is 92.5% silver. The name of United Kingdom monetary unit 'Pound' originally had the value of one troy pound of sterling silver. \nThe malleability, non-toxicity and beauty of silver make it useful in dental alloys for fittings and fillings. \nSilver's catalytic properties make it ideal for use as a catalyst in oxidation reactions; for example, the production of formaldehyde from methanol and air by means of silver screens or crystallites containing a minimum 99.95 weight-percent silver. Silver (upon some suitable support) is probably the only catalyst available today to convert ethylene to ethylene oxide (later hydrolyzed to ethylene glycol, used for making polyesters)—a very important industrial reaction. \nUsed to make solder and brazing alloys, electrical contacts, and high capacity silver-zinc and silver-cadmium batteries \nSilver sulfide, also known as Silver Whiskers, is formed when silver electrical contacts are used in an atmosphere r

How much do you want to spend?\n\nReal gold (99%) is very yellow in color and too soft for normal jewelry (it's soft somewhat like lead).  If you saw real 99% gold you'd never forget it - it is really quite yellow and nothing else looks like it.\n\nFor jewelry, you wouldn't even want real gold, and the things that are added (silver, nickel, etc.) to make it harder always add a 'silver' luster to it (they HAVE to if you think about it - they are silver in color).  Adding copper would shift it to the 'red' side, but it doesn't really make it like the original pure yellow color.\n\nFor gold bullion, you're talking about real money, so if there is any question as to its purity, you can take it to a precision laboratory and they can give you a report on exactly what is in it.  Cost is about $100 for 12 elements, and they will report how much silver, nickel, etc. down to parts per million if you want.\n\nI'd say for jewelry (unless you're going to spend a LOT of money), it isn't worth buying jewelry with a high gold content (partly for the reason you mention).  High gold content jewelry wears out easily and its value is always in question so is impractical (its too expensive to wear).  Buy Krugerands if you want an investment.\n\nBut if you've got money to burn, there is nothing like a real gold necklace or bracelet:  it is heavy, yellow, and feels great on your skin!  But unless you're Donald Trump, it's a waste (I don't think even he would wear pure gold).  The only reason to do it:  because YOU like it.\n\nDensity measurements would confirm solid gold, but they are a little tricky to perform and the accuracy isn't as high as the analytical measurements.\n\nThere is one test you can easily perform: ever heard of the acid test?  You can dunk the jewelry in acid, and if it starts foaming and dissolving, it's not pure gold - but then again, jewelry should not BE pure gold.

Buying spot silver is the best decision here.  In the futures markets there are somewhat arcane delivery rules, i.e. wheat may need to be delivered to a specific railyard and you are responsible for transport from there.  \n\nAdditionally, silver futures are fairly large contracts, where are you going to store it?  This will naturally cost something too.

Stud or small hoops as everyone said.  But they must be silver.  Gold earing looks terrible on most guys.

You would not want to plate white gold with platinum, you should do this with regular gold for the simple fact that yellow gold is cheaper than white gold so you would be cutting your overheads.

Gold is naturally a yellow color.  White gold is an alloy of gold and another metal.  Here's what I found online:\n\nWhite gold is an alloy of gold and some white metals such as nickel, silver and palladium. White gold can be 9k, 10k, 12k, 14k, 18k, or any karat up to 24k. For example, 18k yellow gold is made by mixing 75% gold with 25% other metals such as copper and zinc. 18k white gold is made by mixing 75% gold with 25% other metals such as nickel, silver and palladium. So the amount of gold is the same but the alloy is different.

Personally, I like yellow gold, because it looks richer, and brings out the colors of the stones better. White gold makes my skin look too pale.

its not about gold anymore, countries dont have to back up there money with gold.\nIts all about market and macroeconomics.  Which one people feel more secure and use this countries bank instead, percieved value blah blah and then blah, also blah blah blh, cannot foget about blah blah ...

Many of our metals are solid and homogeneous.  Homogeneous does not mean pure (only one thing) -- it only means that the composition is the same throughout the object.\n\nSo gold yes, or silver.  Also many wooden objects, glass, some food items like the center of bread...  The list goes on forever once you start thinking.

It's "carats". 24k gold is pure. 18k gold is 18 parts of gold with 6 of some other metal, silver, or copper to alter the colour or make it wear harder and last longer, 9k is 9 parts of gold and 15 of other metals.

A pound of cotton is heavier than a pound of gold.\n\nAn ounce of gold is heavier than an ounce of cotton.\n\nPrecious metals are measured using a different system (the Troy system) than most other things.  In this system, the ounce is slightly larger but the pound contains fewer ounces.\n\nLook up Troy weight on Wikipedia to get the exact difference.

To put it most simply, Copper is a metal and sulphur is a nonmetal.  Metals are better conductors of electricity.  If you want to know why metals are better conductors than nonmetals, you should look up band theory.

The basic rule of thumb is any metal.  Silver, gold, iron, copper, and aluminum are a few examples.  Copper is commonly used in electrical wiring because it is durable, inexpensive, and easy to bend.  \n\nAs previous stated, the "gold connectors" on your cables provide very little help.  In pure definition, they conduct electricity more efficiently than copper.  However, the cost delivers little results unless you are investing $50,000 in your home theater sytem.  Then you might tell a difference.\n\nHope it helps!
