Ag (Silver)

   = chemical symbol

Silver is a very ductile and malleable material that is

slightly harder than gold, with a brilliant white metallic

lustre that can withstand a high degree of polishing.

It has the highest electrical conductivity of all metals,

even higher than copper, but its greater cost has prevented

it from being widely used in place of copper for electrical purposes.

Pure silver also has the highest thermal conductivity, whitest

colour, highest optical reflectivity (although it is a poor reflector of ultraviolet light) and the lowest contact resistance of any metal.

Silver halides are photo-sensitive and are remarkable for the effect of light upon them.  This metal is

stable in pure air and water, but does tarnish when exposed to ozone, hydrogen, sulphide or air

containing sulphur. The most common oxidation states of silver are +1 and +2.
