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:
“Walked forth to ease my pain
Along the shore of silver streaming Thames,
Whose rutty bank, the which his river hems,
Was painted all with variable flowers,”
—Edmund Spenser (1552?–1599)
“The intelligent have a right over the ignorant, namely, the right of instructing them. The right punishment of one out of tune, is to make him play in tune; the fine which the good, refusing to govern, ought to pay, is, to be governed by a worse man; that his guards shall not handle gold and silver, but shall be instructed that there is gold and silver in their souls, which will make men willing to give them every thing which they need.”
—Ralph Waldo Emerson (1803–1882)
“And now the chapel’s silver bell you hear,
That summons you to all the pride of pray’r:”
—Alexander Pope (1688–1744)
