Silver

Silver is a chemical element with the symbol Ag and atomic number 47. It is a transition metal known for its shiny, white metallic luster. Silver has been used for various purposes throughout history, including as currency, jewelry, and in various industrial applications.

Physical and Chemical Properties

Silver has a high electrical conductivity, making it useful in electrical contacts and conductors. It is also the most reflective element, which makes it widely used in mirrors and reflective coatings. Silver is relatively soft and malleable, and it has a high melting point.

Chemically, silver is relatively inert and does not react with oxygen or water at normal temperatures. However, it can react with sulfur compounds in the air to form a black tarnish, which is why silver items may require polishing to maintain their luster.

Uses of Silver

Silver has been used for centuries as a currency and as a valuable metal for making coins, jewelry, and decorative items. In modern times, silver is also used in photography, electronics, and as a catalyst in chemical reactions. It is also used in the production of mirrors, solar panels, and medical instruments.
