is a chemical element with symbol Sn and atomic number 50.
It is a main group metal in group 14 of the periodic table.

Fun fact
Tin resists corrosion from water. But strong acids and alkalis corrode it


discovery date 3500 bc ,Tin has been known since ancient times. We do not know who discovered it.The Bronze Age began in about 3000 BC and tin was used in bronze, which contains roughly ninety percent copper and ten percent tin. The addition of tin to bronze alloys improves their properties compared with pure copper: for example, bronze is harder and more easily cast than copper. The ancient Greeks obtained their tin by sea-trade and referred to the source as ‘The Cassiterides’, meaning Tin
Islands.These islands were most likely to have been in Cornwall, Great Britain and/or north-west Iberia,
Spain where there are large tin deposits.

Where does it come from?

Although we think of tin as an everyday material, it's actually much less common than comparable metals such as copper or zinc
(according to the US Geological Survey, copper is over 30 times and zinc about 50 times more common than tin). In terms of abundance, tin is roughly halfway down the list of chemical elements: the 49th most common in Earth's rocky crust, existing in concentrations of about
2 parts per million (0.0002 percent). In other words, if you dig up a tone of rock, a measly 2 grams of it will be tin!

Medical uses
Tin is used for coating lead, zinc of steel to prevent corrosion for hip replacements etc etc. Steel containers coated with tin are commonly used to preserve food. And used to also make wonderful head gear.


Tin can behave as an ‘other metal’ (white tin)
