Silver Silver is a metallic chemical element with the chemical symbol Ag (Latin: argentum, 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. |
L'argent L’argent ou argent métal est un élément chimique de symbole Ag — du latin Argentum — et de numéro atomique 47. C’est un métal précieux dont le nom désigne aussi dans le langage courant les billets et pièces de monnaies mais les économistes distinguent, à la différence du langage courant, l’argent métal de la monnaie comme outil de régulation des échanges économiques. |

| Silver has long been valued as a precious metal, and it is used 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. While many medical antimicrobial uses of silver have been supplanted by antibiotics, further research into clinical potential continues. | L’origine du mot viendrait d’un étymon indo-européen *arg- signifiant « brillant » et serait l’équivalent en sanskrit de ar-jun signifiant « brillant » . | |||||||
