'''Tin''' is a [[chemical element]] with the [[symbol (chemistry)|symbol]] '''Sn''' (from the [[Latin]] word ''stannum'') and the [[atomic number]] 50. It is a soft, malleable, and silvery-white metal classified as a [[post-transition metal]] in [[group (periodic table)|group 14]] of the [[periodic table]].

== Properties ==
| image_caption =
Tin is known for the following physical and chemical properties:
| alt =
* Low melting point (231.93 °C / 449.47 °F)
| symbol2 =
* High resistance to corrosion
| number2 =
* Easily forms alloys with other metals
| pronounciation2 =
* Exists in two main allotropes:
| image2 =
** [[Beta-tin]]: metallic form, stable at room temperature
| image_caption2 =
** [[Alpha-tin]]: non-metallic, gray form that occurs below 13.2 °C
| alt2 =
| symbol3 =
== Occurrence ==
| number3 =
Tin is primarily extracted from the mineral [[cassiterite]] (SnO₂), which is found in:
| pronounciation3 =
* Southeast Asia (notably [[Indonesia]], [[Malaysia]], and [[Thailand]])
| image3 =
* [[China]]
| image_caption3 =
* [[Peru]]
| alt3 =
* [[Bolivia]]
| symbol4 =
* [[Congo]]
| number4 =
| pronounciation4 =
== Uses ==
| image4 =
Tin has a wide range of applications due to its chemical stability and non-toxic nature:
| image_caption4 =
* [[Tin plating]] to prevent corrosion (e.g., in [[tin cans]])
| alt4 =
* Component in [[solder]] (typically mixed with lead or silver)
| symbol5 =
* Production of [[bronze]] (an alloy of tin and copper)
| number5 =
* [[Glass manufacturing]] (used in the float glass process)
| pronounciation5 =
* [[Electronics]] and [[automotive]] industries
| image5 =
| image_caption5 =
== History ==
| alt5 =
Tin has been used by humans since ancient times, notably in the production of [[bronze]] during the [[Bronze Age]]. Its utility as a corrosion-resistant coating and as a soldering material helped drive industrial applications during the 19th and 20th centuries.
| symbol6 =
| number6 =
== Isotopes ==
| pronounciation6 =
Tin is unique among elements in having 10 stable isotopes, more than any other element. Notable isotopes include:
| image6 =
* Tin-120 (most abundant)
| image_caption6 =
* Tin-118
| alt6 =
* Tin-116
| symbol7 =
| number7 =
== Biological Role and Safety ==
| pronounciation7 =
Tin has no known essential biological role in humans. Organotin compounds, however, can be toxic and have environmental and health concerns, particularly those used in industrial and marine applications (e.g., [[tributyltin]]).

Tin has been used by humans since ancient times, notably in the production of bronze during the Bronze Age. Its utility as a corrosion-resistant coating and as a soldering material helped drive industrial applications during the 19th and 20th centuries.
Tin has no known essential biological role in humans. Organotin compounds, however, can be toxic and have environmental and health concerns, particularly those used in industrial and marine applications (e.g., tributyltin).
