Silver

Silver is a chemical element with symbol Ag and atomic number 47. It is a soft, white, lustrous transition metal that possesses the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. Silver occurs in its pure form as native silver and in ores such as argentite and chlorargyrite.

Historically valued as a precious metal, silver has been used for currency, jewelry, and ornaments since ancient times. Its antimicrobial properties make it useful in medical applications and water purification systems. Modern industrial applications include electronics, solar panels, and batteries due to its excellent conductivity.

Silver is also widely used in photography, though digital technology has reduced this demand. The metal is traded as a commodity and often considered a hedge against inflation and economic uncertainty. Silver mining occurs in countries such as Mexico, Peru, and China, which are the world's largest producers.
