Silver

Description:
Silver, with the chemical symbol Ag and CAS number 7440-22-4, is a transition metal known for its distinctive properties and applications. It has a high electrical and thermal conductivity, making it an excellent conductor, which is why it is widely used in electrical contacts and conductors. Silver is characterized by its lustrous, metallic appearance and is highly malleable and ductile, allowing it to be shaped into thin sheets or drawn into wires. Chemically, silver is relatively unreactive, resisting oxidation and corrosion, although it can tarnish when exposed to sulfur compounds in the air. It forms various compounds, including silver nitrate and silver chloride, and exhibits antimicrobial properties, making it valuable in medical applications. Silver is also used in jewelry, photography, and as an investment in the form of coins and bullion. Its isotopes, particularly silver-107 and silver-109, are stable, contributing to its utility in various scientific and industrial applications.
