The elements like gold and Platinum are called the noble elements because . In chemistry the word Noble is used for very unreactive thing and . Also the elements like Gold and the platinum are very unreactive and . They don't form any hydride oxide nitride phosphate sulphate very easily so they are known to be as Noble elements.
So, ewe can imagine my joy and surprise when i discovered that certain metals shared this level of upper hierarchy. look here's one: [ Invalid Attachment ] Platinum Being Well Played By Mike Oldfield Platinum and Gold , Palladium are all known as Noble metals.why's that then ?..what's so noble about them?..They are precious and shiny..I Platinum is often called “white gold”, and believe it or not, platinum is actually way more valuable than gold. Platinum is a member of the platinum group of elements (it’s a little ironic) and it holds the chemical symbol of “Pt”. Platinum is ductile, malleable, dense, and highly unreactive, it has a silvery white look and it often mistaken for silver. This left early humans with the noble metals, many of which are still considered the “precious metals” for jewelers and luxury-seekers around the world – gold, silver, palladium, platinum, rhodium, iridium, ruthenium and osmium. Most of these were so rare, however, that the coins would have to be very small to be able to serve as a In physics, the definition of a noble metal is most strict. It requires that the d-bands of the electronic structure be filled. From this perspective, only copper, silver and gold are noble metals, as all d-like bands are filled and do not cross the Fermi level. However, d-hybridized bands do cross the Fermi level to a small extent. Gold and Silver. Gold doesn't corrode and can be melted over a flame, making it easy to work with and stamp as a coin. Silver and gold are beautiful metals that are easy to form into jewelry, and The best way to invest in platinum is to physically own the metal. Although there are fewer platinum products available than gold or silver, there are still a number of items you can invest in. Platinum bars are a common investment, and these bars typically sell in smaller gram sizes. Coins are another common type of bullion, and a government Some metals are considered precious. The four primary precious metals are gold, silver, platinum, and palladium. Following is a look at what makes a metal precious compared with other metals, plus a list of precious metals.
Why are gold and platinum called noble metals? Gold, silver, and platinum have been called "precious metals" because they are metals and were used to make coins (money) in the days when money

platinum group, including palladium, are con sidered noble metals. — Silver is not considered a noble metal. —A gold-based alloy, commonly called a gold alloy
Noble metal, any of several metallic chemical elements that have outstanding resistance to oxidation, even at high temperatures; the grouping is not strictly defined but usually is considered to include rhenium, ruthenium, rhodium, palladium, silver, osmium, iridium, platinum, and gold; i.e., the metals of groups VIIb, VIII, and Ib of the In physics, the definition of a noble metal is most strict. It requires that the d-bands of the electronic structure be filled. From this perspective, only copper, silver and gold are noble metals, as all d-like bands are filled and do not cross the Fermi level. However, d-hybridized bands do cross the Fermi level to a small extent. Noble metals are metals that are resistant to corrosion or oxidation, unlike most base metals. They tend to be precious metals, often due to perceived rarity. Examples include gold, silver, tantalum, platinum, and rhodium. Some of the noble metals can be dissolved in aqua regia, a highly concentrated mixture of acids. why gold is called noble metal? The precious metals are a subset of the noble metals. While the precious metals gold, silver, platinum, iridium, palladium and sometimes rhodium can be found in jewelry, the most commonly used precious metals are gold, silver and platinum. Gold and silver, along with copper, also are called the coinage or currency metals because of their use in
