Why are gold silver and platinum considered as noble metals
The noble metals are a group of metals that resist oxidation and corrosion in moist air. The noble metals are not easily attacked by acids. Gold , silver and platinum follows all the properties of being Noble metal. Gold (Au) is a noble metal among others that include silver, platinum and gold. Nobel metals are highly resistant to oxidation, which causes rust in other metals, specifically iron (Fe). Gold is a very unreactive metal and is found in its native state in the ground, platinum and silver also behave this way. Other metals that are not of this nature are found mixed in with rocks and The noble metals are gold, silver, platinum, rhodium, iridium, palladium, ruthenium and osmium, with rhenium included on some lists. Noble metals do not oxidize (rust), even at high heat. Noble metal uses include dental alloys, jewelry, coins, microelectronics, spark plugs and cancer treatments. 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 comprise any of several metallic chemical elements that are Nanoscale analogues of gold, silver, platinum, and palladium in particular, have GNPs are considered a potential and powerful therapeutic probe for specific and

Gold. The noble metals are a subset of the metals, but the membership in the group is not well-defined. The strictest definition of a noble metal is metal with a filled electron d-band. According to this definition, gold, silver, and copper are noble metals. Another definition of a noble metal is one which resists oxidation and corrosion. This The noble metals are a group of metals that resist oxidation and corrosion in moist air. The noble metals are not easily attacked by acids. Platinum and gold dissolve in the acid solution aqua regia. On the other side not all corrosion-resistant m The noble metals are a group of metals that resist oxidation and corrosion in moist air. The noble metals are not easily attacked by acids. Gold , silver and platinum follows all the properties of being Noble metal.

In addition to noble metal properties, gold, silver, and platinum posses the following characteristics: These metals occur worldwide, but not in large enough quantities to render them less valuable. They are considered precious metals and have been used as currency (a store of value). Gold and silver have long been esteemed as the king and queen of metals, for good reason. No other members of the mineral family surpass these two metals in nobility. A noble metal is one that is doesn’t oxidize or corrode easily. Gold is the most noble of all metals. It is resistant to air, water, salt, and most acids. Noble Metals gold, silver, platinum, and metals of the platinum group (iridium, osmium, palladium, rhodium, and ruthenium), which received their name owing chiefly to their high chemical stability and beautiful exterior appearance when made into artifacts. In addition, gold, silver and platinum have high plasticity, and metals of the platinum group are 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 had to be made of something that was considered to
Gold is a very unreactive metal and is found in its native state in the ground, platinum and silver also behave this way. Other metals that are not of this nature are found mixed in with rocks and
Traditional metals used in jewelry are the “noble metals”: silver, gold and the platinum metal group (including platinum and palladium). Noble metals are so Rhodium, platinum, gold, ruthenium, iridium, osmium, palladium, rhenium, silver, indium are considered as most expensive precious metals in order of value Apr 23, 2019 The most known precious metals are the gold and silver coinage metals. Other valuable metals include metals from the platinum group: ruthenium, rhodium, Indium is the softest metal not regarded as an alkali metal.
