Tin Element:

Tin is a chemical element. The symbol of Tin is Sn and its atomic number is 50. It belongs to the Carbon family. It is an element in the 14th group and fifth period in the periodic table. Sn is a soft, pliable, silvery-white metal. It is the 49th most abundant element. Sn has 10 stable isotopes and two stable allotropes.

Health Effects:

Tin is mainly applied in various organic substances. The organic tin bonds are the most dangerous forms of  Sn for humans.Tin bond can cause health effects are

  • Eye and Skin irritations
  • Headaches
  • Severe sweating
  • Breathlessness
  • Urination problems
  • Stomach-aches and
  • Sickness and dizziness.



  • Tin element is used as protective coating which shields against rust on steel and other metals.
  • It is also used to coat pins, staples, bronze bell, pewter pitchers and many more such things.
  • It is also used for making  glass windows.
  • The material used in making sprays on glass windows to produce electrically conductive coating for panel lightening and frost-free windshields for cars is made of tin salts.
  • Tin and lead mixture is also used to make solder for electric works.
