Which metal has the chemical symbol Ag?

Silver is the element with the chemical symbol Ag.

The symbol Ag comes from the Latin word argentum. Silver has atomic number 47 and is a soft, bright metal valued for its appearance, reflectivity, and electrical conductivity.

Silver is the most electrically conductive element and also has the highest thermal conductivity of any metal. These properties make it useful in electrical contacts, electronics, solar panels, mirrors, and specialized industrial applications. Its price and softness limit its use as a pure structural material.

Silver tarnishes when compounds containing sulfur react with its surface, forming dark silver sulfide. Tarnishing is a chemical surface reaction, not evidence that the metal has turned into iron or another material. Silver has also been used for coins, jewelry, tableware, photography, and antimicrobial applications. The chemical symbol is easy to confuse with gold's Au, which comes from the Latin aurum.
