What is Tin (Sn Element) ?

  • Tin or also called as Stannum in Latin with the atomic number 50 belongs to the group 14 of the periodic table.
  • Tin shows a chemical similarity to both of its neighbours in group 14, germanium and lead, and has two main oxidation states, and the slightly more stable .

Uses of Tin (Sn Element)

  • It is used in tin plating, coating and polishing as it has high resistance to corrosion
  • It is used in soldering of steel as it possesses high magnetic strengths and lower melting points
  • It is also used in the manufacture of other alloys such as Bronze and copper
  • It is used as a reducing as well as a dyeing agent for glass, ceramics, and sensors
  • In the shipping industry, it is used as an anti-fouling agent for boats and ships to prevent them from barnacles
  • In the dental applications, it is employed in some products in the form of stannous chloride ()
  • It also has its applications in the electrodes of batteries such as in the Li-ion batteries.
  • It is widely used in the manufacture of food containers made of steel.
Uses of Tin

Properties of Tin

  • It has an atomic number of 50 and is known to be a soft and malleable metal in a bluish-white appearance.
  • About two parts/million number of the earth՚s crust is said to be composed of tin.
  • This element exists in the form of igneous rocks of the Earth՚s crust at about a concentration of 0.001 percent, which is assumed to be scarce rather than rare;
  • It is abundantly found like the other elements such as cobalt, copper, nickel, cerium, lead.
  • At room temperature, there is no effect of oxygen and water over the tin. It is also resistant to corrosion. This is the reason it is used as a coating for other metals.
  • At higher temperatures, the metal forms its oxide when reacted with water and oxygen.
  • Tin has about two different forms (or allotropes) which are in the form of white and grey.
  • The grey metal changes its colour to white at temperatures of above and very rapidly above . This metal has about 10 naturally occurring isotopes with different mass numbers.

Health Effects of Tin

  • Sn element in organic form is most dangerous to health. It can cause severe effects in humans such as Eye and skin irritations, Headaches, Sickness, dizziness, Breathlessness, Severe sweating along with Urination problems.
  • The main drawback is that the metal is not completely biodegradable. Hence it can have an impact on the environment.


Tin is Symbolically Represented as ________

Ans: Sn.

What is the Atomic Number of Tin?

Ans: 50.

Tin Belongs to Which Family?

Ans: Carbon family.

Sn Element is a ________ Group Element

Ans: 14th group of the periodic table.

Where is Tin Found?

Ans: It is present in the earth՚s crust mainly in the ore cassiterite.

How is Element Obtained?


  • element is obtained primarily from mineral cassiterite () , and is extracted in a carbon furnace by road sn element cassiterite.
  • sn element constitutes only about 0.001 percent of the Earth՚s crust and is primarily mined in Malaysia. Gray sn element slowly turns at temperatures above into the second form of sn element, white sn element.

What is the Element Used In?


  • element (Sn) , a chemical component belonging to the carbon family, periodic table group 14 (IVa) . It is a smooth, silvery white metal with a bluish element ge, an alloy with copper known to the ancients in bronze.
  • element is commonly used as a food container for element steel containers, in metals used for bearings, and in soldering.

Why is Element So Important?


  • element prevents corrosion, and is used on other metals as a protective coating element. The most common example of this feature is probably the sn element cans. Indeed, a sn element can be made of steel.
  • To prevent the steel from rust element, a thin layer of element is added to both inside and outside the can.
