Silver is a chemical element with the symbol Ag (Latin argentum). A soft white lustrous transition metal, it has the highest electrical and thermal conductivity for a metal, and occurs as a free metal, and in minerals such as argentite and chlorargyrite. Most silver is produced as a by-product of copper, gold, lead, and zinc mining.
