    What is Tin

    Tin is a metal, and chemically it is an element. Tin is a silver-white lustrous metal. Tin is found in two different forms (Allotropes). Its atomic weight is 118.71 AMU, atomic number 50 and symbol Sn. Its atom has 50 electrons, 50 protons, 69 neutrons and 5 energy levels. In the Periodic Table, Tin is located in Group 14, Period 5 and Block P. The density of tin is 7.31 grams per cubic centimeter. Tin is found in the solid state at room temperature, with a melting point of 231 °C (449 °F) and a boiling point of 2602 °C (4715.6 °F).

    Tin metal has been used for thousands of years, so it is unknown who discovered it.

    Properties of Tin Metal

    • Tin is found in two different forms (Allotropes), first white tin and second gray tin. White tin is the silvery-white lustrous metal with which everyone is generally familiar, while gray tin is a non-metallic substance that appears as a gray powder.
    • Gray tin is stable below 13.2 °C, and gray tin gradually changes to white tin above 13.2 °C.
    • White tin is stable at temperatures above 13.2 °C, and white tin gradually turns into gray tin at temperatures below 13.2 °C. If some amount of antimony or bismuth is added to the white tin, this change can be prevented.
    • Tin is a soft and malleable metal, so tin can be easily rolled into thin sheets.
    • Tin has very good corrosion resistance.
    • Tin is a good conductor of electricity and heat.
    • Reacting with oxygen in the air, a thin oxide layer is deposited on the tin, which acts as a protective coating, preventing oxygen from reacting with the tin.

    Uses of Tin Metal

    • Tin is used to make many types of alloys, such as copper and tin metals are mixed together to make bronze, tin and lead are mixed to make solder. Apart from this, alloys like bell metal, babbit metal, type metal etc. are also made from tin only.
    • Tin and niobium metals are combined to make superconductive wire.
    • Tin is used to make a protective coating on steel and other metals to protect them from rust.
    • Tin is used in the production of glass by the Pilkington process, in which molten glass is spread over molten tin, causing the molten glass to float on the surface of the tin. On cooling, a solid glass with very flat and parallel surfaces is formed.
    • Some tin salts are sprayed on glass to form an electrically conductive coating.
    • Tin oxide is used in gas sensors.
    • Tin foil was used for packing medicines and food items, which has now been replaced by aluminum foil.
    • Tin chloride is used as a mordant for dyeing silk and calico.

    Interesting Facts about Tin metal

    • Tin is the 51st most abundant element in the earth's crust.
    • When the tin is bent, a strange sound is produced which is called Tin Cry.
    • Tin does not get rusted in water.
    • The maximum production of tin is done in the countries of South East Asia like China, Indonesia, Myanmar etc.
