What name is given to metals such as gold and silver which are unreactive and not readily subject to corrosion?
Conservation and restoration of silver objects silver objects. Silver is a precious metal that has been mined for use as early as 4000 B.C. in Anatolia (Modern Turkey) Because silver is malleable and durable it has been used for many purposes which include jewelry, tableware, ornaments, coins, musical instruments and movie film. It is often used as a plating on other metals. All metals, apart from pure gold, will corrode naturally when exposed to elements such as air. High relative humidity, moisture, and air pollutants are common causes of corrosion in metals, including silver. Silver is known in the chemistry world as a noble metal which
Corrosion this by removing copper, not the products of copper corrosion. Some metals are more intrinsically resistant to corrosion than others (for some examples, see galvanic series). There are various ways of protecting metals from corrosion (oxidation) including painting, hot dip galvanizing, and combinations of these. The materials most resistant to corrosion are those for which corrosion is thermodynamically unfavorable. Any corrosion products of gold or platinum tend to decompose spontaneously into pure metal, which is why these elements can be found in metallic form on Earth and have long been valued. More common "base" metals can only be protected by
