Are pgm precious metals?

Yes, you can add Rhodium, Irridium and Palladium among others.\n\nBasically it's those elements that have the outer electron d-shell filled completely. They therefore interact weakly with other elements.

Silver is a precious metal, very soft and malleable, and not very useful for use in jewelry because it is so easily damaged.\n\n925 silver is 92.5% silver and 7.5% other metals (commonly copper).  As an alloy, the 925 silver is much harder and can stand up to the wear and tear of being used in jewelry.\n\nStainless steel is an alloy of iron and a minimum of 10% chromium.  Most stainless steel formulations have 13% or more chromium.  Many other metals (nickle, carbon, manganese, molybdenum) are added in small amounts to alter various physical and chemical properties of the alloy.

It's probably real gold, yes.  It's not pure gold, which is 24K.  14K means they added other elements to it to make it stronger.

Composition of Sterling Silver \n\nSterling silver is an alloy consisting of no less than 92.5% silver and 7.5% of some other metal, usually copper.  Copper is added to make the alloy less prone to breakage and scratching.  Sterling silver is about twice as strong as pure silver.\n\nThe 92.5% silver content standard for "sterling" originates in 14th Century England, where King Edward I decreed that silver coins must be stamped with its silver content.  In time, the 92.5 stamp came to be known as "sterling" and the rest is history.  \n\nPerhaps as a result of this successful effort to control the quality of silver items, the term "sterling" itself has come to mean "of the highest quality" (for example, "She has a sterling reputation.")\n\nHistory\n\nSterling silver has been around for nearly as long as silver - at least 60 centuries.  Over the centuries silver has been combined with other metals to make it stronger.  Eventually, it was concluded that copper is the best mate for silver.  While jewelry styles may come and go, sterling silver has always been an alloy of choice to jewelry makers, and probably always well be.\n\nOver the years, sterling silver has also been valued for reasons beyond its beauty.  Some cultures have attributed healing properties to it, while others have believed that it could bring good luck or thwart the plans of evil spirits.  \n\nThroughout Asia,  silver has long been equated with status and wealth.  In ancient Egypt silver was more valuable than even gold.  Over time, silver became an alloy that even those without great wealth could afford, usually as jewelry. One did not need to be born with the proverbial "silver spoon" in his or her mouth to have a sterling silver adornment.\n\nSterling silver is also equated in some cultures with certain ceremonials or milestones.  For example, Germany is generally credited with treating the 25th wedding anniversary as the "silver anniversary."/

The value of precious metals, as well as gems, are based on their rarity. It may seem like there is a lot of gold all around us, but the amount of gold available on the earth is finite. Other metals, like platinum or even rarer. Gold has always been precious because it does not tarnish or rust. \n  The world's economic system no longer relies on just precious metals. If it were, it would be a disaster. During WWII, dollars were issued not on what they were actually worth in gold, but what the were promised to be worth... and we know how governmental promises work. Then other governments issued their money based on what our money was worth... pretty soon all money was going to be worthless.  Now each country's economic system is based on all its assets, including industry and natural resources. That is why money values fluctuate so much every day.

it is a noble gas, but just because something isnt solid doesnt meanits a nonmetal. metals all become gasses at high temperature. the metals are on the left side of the periodic tabl and the non metals arre on the right. xenon is all the way on the right so its a non metal.\n\nhttp://en.wikipedia.org/wiki/Periodic_table#Standard_periodic_table

Just Google or Yahoo search gold bullion. There are a lot of markets, but some are futures and some are syndicates or associations that sell you a share of their value, not gold itself. Most small quantities of gold are sold as coins.\n\nSee, for example: http://www.bulliondirect.com/catalog/home.do;jsessionid=F197EC28F228F08EFC252A22BAC41FDF

Pure Gold is an element, Au.\n\nHowever, the gold you get from shops are not pure gold, but are alloys with other compound, since pure gold is soft at room temperature.

An ETF (Exchange Traded Fund) for silver will be coming to the market soon. I think it's a Barclay iShare (www.ishares.com). If you want the physical metal look at www.apmex.com they're pretty good.

All s, d, and f elements are metals.\n\nBlock p includes metals, non-metals, and some metaloids in between.  Metals include Aluminum and down in that group.  Tin and down in that group. and Polonium in its group.  So the lower left corner of the p block are metals and the upper right corner are non-metals.  Boron, Silicon, Germanium, Antimony, and Tellurium, tend to be considered metaloids.  (Depends on who you read.)

The platinum group or platinum metals is the collective name sometimes used for six chemical elements within the periodic table. These elements are all transition metals, lying in the d-block (groups 8, 9, and 10, periods 5 and 6 - in Mendeleev's original table, this area was called "Group VIII").\n\nThe six platinum metals are: ruthenium, rhodium, palladium, osmium, iridium, and platinum. They have similar physical and chemical properties, and tend to occur together in the same mineral deposits.

This is really hard to answer. It's not like there is some New York Element Exchange where traders buy and sell elements. If you mean what is the monetary value of an element, there are some that are pretty easy to determine,  since metals like gold, silver, platinum, palladium, aluminum, copper, and other metals are used in industry. But if you want to know the cost of hafnium, then you aren't going to find any one answer, if you can find one at all. \n\nIf you want to see what the metals market prices are go here:http://www.metalprices.com/\nThat will give you most of them. If you want to see the cost of gases for industrial use, like nitrogen, oxygen, hydrogen, helium, you'll have to contact someone like Praxair or Airgas to get a quote.\nhttp://www.praxair.com/praxair.nsf/0/6021E2747E378CF285256B9F0070368D?OpenDocument
