Gold: Most Sought-After Precious Metal
Of all the different precious metals we can think of, gold is certainly the one most greatly desired. Since the beginning of recorded history, gold has been in use in many different works of art, coinage, and, of course, jewelry.

The Eight Precious Metals Considered Noble Metals
Most metallic chemical elements are known to easily oxidize and corrode, especially at high temperatures. Metals that have excellent resistance to oxidation and corrosion, even at high temperatures, are called noble metals. While there is no strict definition for this group of metals, it usually includes those that are extremely rare. Thus, metals that are labeled "precious" are also considered noble metals (note, however, that noble metals are not necessarily precious metals). There are nine known precious metals - gold, platinum, iridium, palladium, osmium, silver, rhodium, ruthenium, and rhenium. With the exception of the latter, all are considered noble metals. Using the ...
