Silver. Silver, taken from the Latin name, argentium, is of ancient origin. Its products and refining methods are described in the Bible and early Egyptian writings. Silver occurs as the metal and in silver ores such as argentite (Ag 2 S). Such sulphide ores often accompany copper, lead, and zinc ores. Silver is found in many parts of Canada.

· Silver''s Physical Properties It is an extremely soft, ductile and malleable transition metal, though it is slightly less malleable than gold. Crystallizes in a face-centered cubic lattice with bulk coordination number 12, where only the single 5s electron is delocalized, similarly to copper and gold.
Electrical properties. The electrical conductivity of a metal (or its reciprocal, electrical resistivity) is determined by the ease of movement of electrons past the atoms under the influence of an electric field. This movement is particularly easy in copper, silver, gold, and aluminum—all of which are well-known conductors of electricity.
Silver has the highest known electrical and thermal conductivity of all metals and is used in fabricating printed electrical circuits and as a vapour-deposited coating for electronic conductors; it is also alloyed with such elements as nickel or palladium for use in electrical contacts.
