Some Interesting Tid Bits About Silver…Or As Some Call It – Poor Man’s Gold

Posted By on September 12, 2013

Silver appears to be the metal of the future….especially when one considers that 2/3 of all silver produced worldwide is a by product of lead, copper and zinc mining.

Major silver users include the electronic and circut board industry, water purification and growing  industrial uses in China, including production of energy saving solar panels.

Silver

Atomic Number: 47

Symbol: Ag

Atomic Weight: 107.8682

Discovery: Known since prehistoric time. Man learned to separate silver from lead as early as 3000 B.C.

Electron Configuration: [Kr]5s14d10

Word Origin: Anglo-Saxon Seolfor or siolfur; meaning ‘silver’, and Latin argentum meaning ‘silver’

Properties: The melting point of silver is 961.93°C, boiling point is 2212°C, specific gravity is 10.50 (20°C), with a valence of 1 or 2. Pure silver has a brilliant white metallic luster. Silver is slightly harder than gold. It is very ductile and malleable, exceeded in these properties by gold and palladium. Pure silver has the highest electrical and thermal conductivity of all metals. Silver possesses the lowest contact resistance of all metals. Silver is stable in pure air and water, although it tarnishes upon exposure to ozone, hydrogen sulfide, or air containing sulfur.

Silver is the best conductor of electricity of all elements. In fact, silver defines conductivity,  all other metals are compared against it. On a scale of 0 to 100, silver ranks 100, with copper at 97 and gold at 76. Silver is commonly used in electrical circuits and contacts. Silver is also utilized in batteries where dependability is mandatory and weight restrictions apply, such as those for portable surgical tools, hearing aids, pacemakers and space travel.

80% more conductive than aluminum
