Tin is a silvery-gray metallic element which has been used by humans for thousands of years. The symbol is

Sn, from the Latin stannum, and its atomic number is 50, placing it with other metals such as antimony and aluminum. Almost every continent on Earth has a source of tin, usually in the form of cassiterite, an oxide mineral. In addition to a wide range of manufacturing uses, the metal is also nutritionally necessary, albeit in trace amounts.

The word for the metal appears to have been borrowed from a pre-Indo-European language. Old forms of

German and Dutch, among other languages, have cognates for the word, but the roots are somewhat unclear. The murky etymology of the word supports research by anthropologists which suggests that humans have been interacting with tin for at least 5,000 years, if not longer.

Studies of early humans have suggested that tin was one of the earliest metals used by humans. It was

alloyed with copper to make bronze, making it one of the earliest alloyed metals. In retrospect, tin is an

obvious choice for a copper alloy, because it hardens copper when the metals are blended. Tin was also

used in the production of ornaments and jewelry. As human innovation progressed, the metal began to be harnessed for other purposes as well. Its high corrosion resistance make it an excellent choice for coating,

and for making alloys with other metals.
