Supposedly it's illegal though (I'm giving away my age)...I remember when there was a big rush up in the price of silver to $50+ per ounce and coin dealers and antique shops were all rusing material to smelters (technical term for those who melt/refine metals).  Nobody was ever arrested for it that I'm aware of.  Numismatic value is determined by the date, mint, and condition of the coin so I'd check the Redbook at the library to see if the coin is worth more than melt (melt is currently at around 6x face for silver).

Gold is usally found in veins in mines.  This is after yearssssss of a couple different mixtures that could happen with elements and combounds that get really complicated an messy.  But, scientist have created a particle accelerator that shots atoms at one another to created a desired "pure" element, but this mechine is about the size of a football feild or so and the chamber that the bombarding happens in is a room as big as your average class room and it only produces just enough gold to little dust the tip of a sewing neddle.

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.

Hello,\n\n    The quotes below are taken from the Stillwater Mine web site. The deposit this mine uses in Montana is the largest palladium deposit in the world and unusual in that it contains much more palladium than platinum:\n\n"The platinum group metals (PGM) occur both in primary deposits and placers. The primary deposits are of two main types. The first consists of local concentrations of the metals in olivine-rich rocks, particularly in dunite. Often associated with chromite, native platinum or iridosmine is the principal constituent. The erosion of such deposits has been responsible for the formation of placer deposits of the platinum metals. The most important commercial dunite deposits are in the Ural Mountains of Russia and at the Overwacht in the Transvaal in South Africa. \n\nThe second type of primary deposit includes nickel-copper sulphide deposits that are generally associated with norite. These deposits, in which platinum and palladium predominate, make up the greatest known reserves of PGM metals. The most extensive deposits have been found in the norite belt of the Bushveld Igneous Complex in the Transvaal, the Stillwater Complex in Montana, USA, in the Sudbury district of Ontario Canada and the Norilsk Complex in Russia."\n\n    I hope that helps,\n\n    Steve

Sulfur can often be found around fumerals and hotsprings in highly volcanic areas.  If I remember correctly, I've seen some deposits in Yellowstone and in Hawaii Volcanos National Park.\n\nWikipedia has an article which describes other places to find sulfur.

It is believed that Albertus Magnus obtained the element in 1250 A.D. who obtained it by heating soap together with orpiment (arsenic trisulphide, As2S3). But actually Arsenic has been known since ancient times. It is so old, nobody knows who first discovered it or when. Arsenic compounds were mined by the early Chinese, Greek and Egyptian civilizations. No doubt they discovered its toxic properties early on. I don't know if anybody could find a name from the ancient history.

Miners used mercury (quicksilver) to recover gold throughout the western United States at both placer (alluvial) and hardrock (lode) mines. The vast majority of mercury lost to the environment in California was from placer-gold mines, which used hydraulic, drift, and dredging methods. At hydraulic mines, placer ores were broken down with monitors (or water cannons, fig. 1) and the resulting slurry was directed through sluices and drainage tunnels, where gold particles combined with liquid mercury to form gold-mercury amalgam. Loss of mercury in this process was 10 to 30 percent per season (Bowie, 1905), resulting in highly contaminated sediments at mine sites (fig. 2). Elevated mercury concentrations in present-day mine waters and sediments indicate that hundreds to thousands of pounds of mercury remain at each of the many sites affected by hydraulic mining.\n\n\nhope that helps

gold is and element, silver, copper, water is hydrogen and oxygen, everything is made of elements!  If your just having trouble finding the periodic table, try spelling it p-e-r-i-o-d-i-c.

Mercury is the only common metal liquid at ordinary temperatures and rarely occurs free in nature.  \n\nIt is a heavy, silvery white metal; a rather poor conductor of heat, as compared with other metals, and a fair conductor of electricity.  It easily forms alloys with many metals, such as gold, silver and time which are called amalgams.  \n\nThe metal is widely used laboratory work for making thermometers, barometers, diffusion ion pumps and many other instruments. Mercury should be handled with care because of the absorbing through the skin and can cause many problems (very serious ones).

Magnesium and zinc are heavy metals , Gold is light , It does not corrode and is shiny too.It is malleable and Ductile !\nGold has several qualities that have made it exceptionally valuable throughout history. It is attractive in colour and brightness, durable to the point of virtual indestructibility, highly malleable, and usually found in nature in a comparatively pure form. \nSoft, lustrous, white silver was one of the first metals known to humans. Together with gold, iridium, palladium, and platinum, it is one of the group called precious metals. Silver ornaments and decorations have been found in royal tombs dating back as far as 4000 BC.Silver is somewhat harder than gold and is second only to gold in malleability and ductility.\nSame is with silver\nRegards,\nSidra

Gold comes from the earth and is found in two major kinds of deposits. One of these is called a placer deposit, which is a name for an accumulation of gravel and sediment that has been deposited by a stream. The gold in these deposits actually originated in the other type of deposit, but was eroded away and carried to a place where the stream slowed enought that it could not  move the heavy gold. \n\nThe primary gold deposit is known as a lode or vein. These are thought to be deposited by circulating geothermal waters that move upward into the earth along cracks and fissures created by volcanic rocks that are also pushing upward. Another possible method of depostion may be that gold is coming from solutions that originate in igneous rocks that are cooling in the subsurface. \n\nSome of the largest deposits of gold are in very low concentration (<<1%)deposits of ore called porphyry deposits. These deposits often are mined primarily for copper, lead, zinc, or silver and gold is produced as a byproduct. However, the largest single source of gold in the US is the Bingham Canyon Mine in Utah which has produced about 18 million troy ounces of gold. Most porphyry deposits are believed to have originated by migration of fluids from deep areas of volcanic activity.

I don't really understand your question.  However, the higher up a metal is on the reactivity series the more reactive it is.  That means it likes making compounds with other things.  The less reactive a metal is the more likely you are to find it as an element in an uncombined form.\n\nThe earliest metals to be discovered were generally those that were uncombined in the ground or very easy to separate from the compounds they were found in.  So the least reactive metals were first to be discovered and used.\n\nThe most reactive metals were not discovered for thousands more years because they are only found in compounds, never as the metals themselves and are very difficult to extract from their ores.  Electrolysis has to be used to separate the reactive metals, so they were not discovered until electricity was in use.

Removing tarnish from silver jewelry is a chemical reaction that gets a lot of use in my daily life. :)
