Gold got its name from the Anglo-Saxon word for the element, which is simply "gold." The word might have been influenced by the Sanskrit word for gold, which is "jval." The chemical symbol for gold is "Au." This is an abbreviation of "aurum," which is the Latin word for gold.Know More
Gold is an element that's been known for thousands of years, and no one knows who was first to discover it. It's a metal that is exceptionally ductile and malleable. This means it can be pulled into the thinnest of wires and beaten into the thinnest of sheets without breaking. It's one of the few elements that is a natural gold color. Most metals are gray, white or silver.
Gold doesn't tarnish. A gold doubloon retrieved from the wreck of a Spanish galleon is as brilliant in 2014 as it was when it was put on the ship in the 16th century.
Gold is also resistant to most acids. A solution called aqua regia is used to dissolve gold. Gold is also very dense; 24-karat gold is pure gold. The drawback with pure gold is that it's too soft for everyday wear; because of this, it's always alloyed with another metal to create jewelry.Learn more about Precious Metals & Gems

According to About.com expert Dr. Anne Marie Helmenstine, the simplest way to determine if an element is a metal is to see if it appears with the other metals on the periodic table. There are 117 non-theoretical elements on the periodic table, and all but 17 are either metals or metalloids. Scientists also use chemical experiments to determine if a sample of indeterminate nature contains metal ions.Full Answer >
There is no record that states when gold was discovered, but it is known to have been used by human beings since at least 3000 B.C. A fairly stable element, gold can be found in a free state, often in stream beds.Full Answer >
