Properties:
Lustrous, hard, malleable and ductile metal.
Compounds:
Chloride, halide, iodide, nitrate sulfide.
Uses:
Coinage, silverware, jewelry, electrical devices.
Hazard:
Most silver salts are poisonous. Silver compounds can be absorbed in the circulatory system and cause argyria.

Silver is a chemical element, typically found as a solid in its elemental form. It has the chemical symbol Ag (from the Latin argentum), atomic number (number of protons) Z = 47, and a standard atomic weight of 107.8682 g/mol. At normal atmospheric pressure and typical room temperatures, silver is a hard, lustrous, malleable and ductile solid. It is considered to be a member of the "Transition metal" class of elements.

Silver has been known and used by mankind since ancient times, and is commonly regarded as one of the precious metals, along with gold and platinum. Today, silver is often used in electrical devices (such as electrical contacts and wires) and jewelry.[1] It was once used extensively to mint coins and as an antibacterial agent before the discovery of antibiotics (though today silver in colloidal form is still sold as a dietary supplement in the United States of America).

## Properties[edit]

At a pressure of 101.325 kPa, it has a boiling point of 2,162 °C and a melting point of 961.78 °C.[1] It's density is 10.5 g/cc.

Silver has the highest electrical and thermal conductivity among all metals. Its chemical reactivity is quite low, but can tarnish in the presence of ozone, hydrogen sulphide, or air mixed with sulphur.[1]
