Is silver a noble metal

Noble metals are used in the manufacture of mirrors (silvering of glass with solutions or by vacuum-dusting with silver). The casings of high-altitude aviation engines are covered inside and out with a very thin film of noble metals. 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.

Atomic number is prominent among these criteria. All metals have unique characteristics and hence they have different atomic numbers and other properties. In the  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 excludes copper, but adds in other platinum group metals, such as rhodium, palladium, ruthenium, osmium, and iridium. 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. Originally Answered: Is silver a noble metal? We tend to refer to that group as the coinage metals. Cu, Ag and Au don't have the same rich chemistry that the other transition metals have, but they still have a great deal of incredibly interesting chemistry. They are by no means equivalent to the noble gases. Here is a list of noble metals, which are metals that resist oxidation and corrosion. ruthenium; rhodium; palladium; silver; osmium; iridium; platinum; gold; Noble metals oxidize less readily than other metals because their outer valence shell of electrons is full. Here is a link to the Wikipedia page on Noble Metals Noble metal - Wikipedia. Silver is a precious metal because it is rare and valuable, and it is a noble metal because it resists corrosion and oxidation, though not as well as gold. Because it is the best thermal and electrical conductor of all the metals, silver is ideal for electrical applications. Its antimicrobial, non-toxic qualities make it useful in medicine and consumer products.

Noble metal definition is - a metal (as gold, silver, or platinum) or alloy relatively superior in resistance to corrosion or oxidation —opposed to base metal. Noble metals are used in the manufacture of mirrors (silvering of glass with solutions or by vacuum-dusting with silver). The casings of high-altitude aviation engines are covered inside and out with a very thin film of noble metals. 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.

Silver is a noble metal with the highest electrical conductivity of any element. It also has the highest thermal conductivity of any metal, and is an excellent optical reflector. Not only has silver been used as currency, but also it is widely used in jewelry, tableware, electronics, x-ray and other medical and dental films and photographic prints.

We are recovering rare metals, such as gold, silver, platinum, palladium, nickel, aluminum, copper, tin and lead, from metal scraps of electronic parts, PCB, etc. and 

Noble Metals is a non-ferrous metal processor buying and selling metal products. We recycle, recover, refine and market metals.
