Silver is a chemical element with the chemical
symbol Ag (Latin: argentum, from the Ancient Greek:
ἀργήεντος
- argēentos, gen. of ἀργήεις
- argēeis, "white, shining" ) and
atomic number 47. A soft, white, lustrous transition
metal, it has the highest electrical conductivity
of any element and the highest thermal conductivity
of any metal. The metal occurs naturally in its
pure, free form (native silver), as an alloy with
gold (electrum) and other metals, and in minerals
such as argentite and chlorargyrite. Most silver
is produced as a by-product of copper, gold, lead,
and zinc refining.

Jewelry
Silver has been known since ancient times and
has long been valued as a precious metal, used
to make ornaments, jewelry, high-value tableware,
utensils (hence the term silverware), and currency
coins. Today, silver metal is used in electrical
contacts and conductors, in mirrors and in catalysis
of chemical reactions. Its compounds are used
in photographic film and dilute solutions of silver
nitrate and other silver compounds are used as
disinfectants. Although the antimicrobial uses
of silver have largely been supplanted by the
use of antibiotics, further research into its
clinical potential is in progress.
