Chemistry - Silver

Introduction

  • 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.

Silver

  • 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.
