Silver (Ag) is a metallic chemical element with atomic number 47. It has been given the symbol Ag because of its Latin name, argentum.
Silver has several unique properties, for instance it is more conductive and more reflective than any other metal, and it therefore has many industrial applications. For example, it is used in electronics and solar panels.
Silver, along with gold which is in the same group in the periodic table, have a long history of being used as money, and they're both still used as investments today in the form of coins and bullion.
Other uses of silver include jewellery and silverware. Silverware such as cutlery is often made of sterling silver (a silver-copper alloy) rather than pure silver, since sterling silver is harder.
There are two stable silver isotopes, 107Ag and 109Ag, and they're more or less equally abundant.
