The discovery of tin is unknown as the time or the location of discovery was dated long back. Tools or weapons including tin was discovered by human’s years ago in 3,000 BC. Tin is the oldest man-made object that contain tin is the Bronze. Bronze is the element that contains both copper and tin. Historians reveal that tin was extracted for manufacturing and trading in Britain and Spanish Islands where it was found the most. Tin is the 49th most rich element in the earth’s crust, having 2 parts per million compared with 75 parts per million for zinc, 50 parts per million for copper, and 14 parts per million for lead.

Characteristics of Tin

  • Tin is a soft and malleable metal.

  • Ductile and crystalline silvery-white metal.

  • It melts at low temperature of around 232 °Celsius (450 °Fahrenheit).

  • There are 2 kinds of allotropes beta-tin the metallic form, or white tin and alpha-tin or grey tin.
  • White tin or metallic form which is stable at room temperature is malleable.

  • Grey tin stable below 13.2 °Celsius is brittle.

  • Grey tin has non-metallic properties because it has covalent structure.

  • In cold condition, white tin tends to transform into grey tin which is known as “Tin pest”.

How many isotopes does Tin have?

Tin has 10 stable isotopes. Tin, with its three common isotopes 116Sn, 118Sn and 120Sn, is among the easiest elements to detect analyze by NMR spectroscopy. NMR spectroscopy is a research methodology that explores on magnetic properties of the atomic nuclei. This study helps in determining the physical and chemical properties of the atoms or molecules.

Etymology of Tin.

In Latin Stannum means mixture of silver and lead that meant ‘Tin’ which was further renamed in Latin as plumbum candidum. It has a common etymology that include “Zinn” in German, “Tenn” in Swedish and “Tin” in Dutch.

Occurrence of Tin

Tin occurs based on the extraction from various ores. Cassiterite is the commercial source of tin. Small quantities of tin are recovered from sulfides such as stannite, cylindrite, franckeite and teallite.

80% of mined tin is from secondary deposits found in the downstream from the primary lodes. It is because of the higher specific gravity of tin dioxide. Tin is often recovered from particles washed from the downstream of the valleys of the sea. Tin in general is produced from the placer deposits.

Applications of Tin in modern industry

Tin-plated steel which is known as pierced tin is technique for manufacturing housewares in central Europe. The pierced design applied on the decorative light is used for artistic purposes. Window glasses are often made form molten glass on molten tin. Tin fluoride is a component added to dental care products. It is also used as electrode in Li-ion batteries.
