Silver is a metallic chemical element with the chemical symbol Ag (Greek: άργυρος <árgyros>, Latin: argentum, both from the Indo-European root *arg- for "grey" or "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 and other metals, and in minerals such as argentite and chlorargyrite. Most silver is produced as a byproduct of copper, gold, lead, and zinc refining.
Silver has long been valued as a precious metal, and is used as an investment, to make ornaments, jewelry, high-value tableware, utensils (hence the term silverware), and currency coins. Today, silver metal is also used in electrical contacts and conductors, in mirrors and in catalysis of chemical reactions. Its compounds are used in photographic film, and dilute silver nitrate solutions and other silver compounds are used as disinfectants and microbiocides (oligodynamic effect). While many medical antimicrobial uses of silver have been supplanted by antibiotics, further research into clinical potential continues.

Famous quotes containing the word silver:
Of cloudy silver sprinkles in your gown
Its venom of renown, and on your head
No crown is simpler than the simple hair.”
—Wallace Stevens (18791955)
“By what a delicate and far-stretched contribution every island is made! What an enterprise of nature thus to lay the foundations of and to build up the future continent, of golden and silver sands and the ruins of forests, with ant-like industry.”
—Henry David Thoreau (18171862)
“This royal throne of kings, this sceptred isle,
This earth of majesty, this seat of Mars,
This other Eden, demi-paradise,
This fortress built by nature for herself
Against infection and the hand of war,
This happy breed of men, this little world,
This precious stone set in the silver sea,
Which serves it in the office of a wall,
Or as a moat defensive to a house
Against the envy of less happier lands;
This blessèd plot, this earth, this realm, this England.”
—William Shakespeare (15641616)
