Silver is also a very popular metal. Like gold, silver is a rare metal and holds great value and is also traded in similar markets. Silver is also a popular metal to make jewelry with because of both its rarity and malleability. For some time, silver was also used in dentistry, although it had to be mixed with mercury because it is not quite as malleable as gold. Silver is also a good conductor and is used in electroplating. It is also used in the manufacturing of batteries as well as a catalyst.
