Is silver noble metal
Silver is a precious metal that is commonly used in jewelry as well as in daily utensils, tools, and various other objects. Next to gold, silver was once used by 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. 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. Silver and gold, which with copper are often called the coinage metals, and platinum, iridium, and palladium comprise the so-called precious metals, which are used in jewelry.

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.

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.

The 8 most common noble metals include Gold (Ag), Silver (Au), Platinum (Pt), Rhodium (Rh), Iridium (Ir), Ruthenium (Ru), Osmium (Os) and Palladium (Pd). As you likely know, the first 3 are often used in making jewelry or other ornaments. The sole reason for this is their inertness and resistance to change when exposed to air. The most common medical compounds containing noble metals include silver nitrate and Piotargol (silver protein). Noble metals are used in radiation therapy (needles of radioactive gold to destroy malignant tumors) and in compounds that increase the defensive abilities of the organism.
