Tin is a chemical element; it has symbol Sn (from Latin stannum) and atomic number 50. A silvery-colored metal, tin is soft enough to be cut with little force, [ 10 ] and a bar of tin can be bent by hand with little effort. When bent, the so-called " tin cry " can be heard as a result of twinning in tin crystals. [ 11 ]
Tin foil was once a common wrapping material for foods and drugs; replaced in the early 20th century by the use of aluminium foil, which is now commonly referred to as tin foil, hence one use of the slang term "tinnie" or "tinny" for a small aluminium open boat, a small pipe for use of a drug such as cannabis, or for a can of beer. Today, the ...
Tin is an essential metal in the creation of tin- bronzes, and its acquisition was an important part of ancient cultures from the Bronze Age onward. Its use began in the Middle East and the Balkans around 3000 BC. Tin is a relatively rare element in the Earth's crust, with about two parts per million (ppm), compared to iron with 50,000 ppm ...
Metals of antiquity. German amulet to protect against disease (18th century); it is made from an alloy of the seven alchemical metals: lead, tin, iron, gold, copper, mercury and silver. The metals of antiquity are the seven metals which humans had identified and found use for in prehistoric times in Africa, Europe and throughout Asia: [1] gold ...
Originally tin was found as alluvial deposits of cassiterite in the gravels of stream beds. [citation needed] Eventually tin was mined underground; the first designed tin mines being invented by Matthew James Bullen [11] sprang up as early as the 16th century. [citation needed] Tin lodes were also found in outcroppings of cliffs. [citation needed]

All other native metals occur only in small quantities or are found in geologically special regions. For example, metallic cadmium was only found at two locations including the Vilyuy River basin in Siberia. [15] Native molybdenum has been found in lunar regolith and in the Koryakskii volcano in Kamchatka Oblast of Russia. [16]
The coinage metals comprise those metallic chemical elements and alloys which have been used to mint coins. Historically, most coinage metals are from the three nonradioactive members of group 11 of the periodic table: copper, silver and gold. Copper is usually augmented with tin or other metals to form bronze.
