Tin is a chemical element with the symbol Sn, derived from the Latin name stannum, and it has atomic number 50 on the periodic table, placing it in group 14 alongside carbon, silicon, germanium, and lead. Tin has a name shared across Germanic languages, with related words like German “Zinn” and Dutch “tin,” tracing back to Proto-Germanic origins. In the Romance languages, its name clearly reflects its Latin root, such as estaño in Spanish, stagno in Italian, and stagn in Romanian.

Tin is a soft, silvery-white metal that is so malleable it can be cut with little force and even bent easily by hand without breaking.

When a bar of tin is bent, it can produce a distinctive crackling sound known as the “tin cry,” caused by twinning in its crystal structure.

Tin exists in two main allotropes, with white beta tin being stable at room temperature and gray alpha tin becoming stable at low temperatures below 13.2 °C.

The transformation of white tin into brittle gray tin at low temperatures is known as “tin pest” or “tin disease,” which can cause the metal to crumble.

A persistent historical (mostly false) legend claims that tin pest contributed to the failure of Napoleon’s army during the 1812 Russian campaign by destroying uniform buttons.

Tin melts at about 231.93 °C, making it the lowest melting point among group 14 elements, which helps explain its use in alloys and solder.

Tin has a boiling point of about 2602 °C, which is unusually high compared to its relatively low melting point, showing a wide liquid range.

White tin is denser than gray tin, which is one reason the metal changes structure dramatically when shifting between allotropes.

Tin becomes superconducting at extremely low temperatures below 3.72 K, making it one of the earliest known superconducting materials.

Tin has an unusually high number of stable isotopes, with ten recognized stable forms, the most of any element in the periodic table.

The most abundant isotope of tin is tin-120, which makes up roughly one third of all naturally occurring tin.

Tin is relatively rare in Earth’s crust, making up only about 0.00022 percent, yet it is still the 49th most abundant element overall.

The primary ore of tin is cassiterite, a mineral composed mainly of tin dioxide (SnO₂), which is mined worldwide.

Tin has been used since the Bronze Age around 3000 BC, especially in alloys with copper to create bronze, which revolutionized tools and weapons.

Bronze typically contains about 12.5 percent tin and 87.5 percent copper, producing a harder and more durable metal than copper alone.

Pewter, a historical alloy used for tableware, usually contains 85 to 90 percent tin mixed with small amounts of other metals.

Tin is a key component in solder, where it is often mixed with lead in a eutectic ratio that melts at about 183 °C.

Modern lead free solders still rely heavily on tin, often combined with copper and silver to replace older toxic formulations.

Tin plating is widely used to coat steel and prevent corrosion, which is why food cans are often called “tin cans.”

Tin cans were first mass produced in London in 1812, marking a major advancement in food preservation technology.

Tin forms a protective oxide layer when exposed to air, which helps it resist corrosion and increases its durability, making it much better in this regard than iron and its tendency to rust.
