Chemistry - Silver
Silver is a soft, lustrous transition, and white metal.
Silver has the highest electrical and thermal conductivity; and, it has also the highest reflectivity of any metal.
The symbol of silver is ‘Ag’ and atomic number is ’47.’
Salient Features of Silver
Silver is a precious metal used since long time by human beings.
Silver is an element of group 11 of the periodic table.
Silver has an excellent white metallic luster commonly used in a high polish.
As silver has no color; therefore, it has high reflectivity (of light).
Silver has very high electrical and thermal conductivity. Its electric conductivity is the highest – higher than copper.
Among all the metals, silver also has the lowest contact resistance.
Occurrence of Silver
The metal silver is usually found in the Earth's crust in the pure form.
Silver also found as an alloy with the gold and some other metals.
Silver is also found in some minerals, such as argentite and chlorargyrite.
Silver is largely produced as a byproduct of gold, copper, zinc, lead, etc.
