Silver
Silver is a chemical element with symbol Ag (from the Latin "", derived from the Proto-Indo-European "h₂erǵ": "shiny" or "white") and atomic number 47. A soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. The metal is found in the Earth's crust in the pure, free elemental form ("native silver"), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Most silver is produced as a byproduct of copper, gold, lead, and zinc refining.
Emblem of the Azerbaijan Soviet Socialist Republic
The emblem features a drilling rig representing Baku's wealthy oil reservoirs and, behind it, a sunrise, standing for the future of the Azeri nation. The hammer and sickle are prominently featured above it while the red star (symbolizing "socialism on all five continents") sits at the top of the emblem, for the victory of Communism and the "world-wide socialist community of states". The outer rim features symbols of agriculture — wheat and cotton.
