What is Tin?
- 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 neighbors in group 14, germanium and lead, and has two main oxidation states, +2 and the slightly more stable +4.
Uses of Tin
- 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 dyeing agent for glass, ceramics, and sensors
- In the shipping industry, it is used as an antifouling 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.
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 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 called as allotropes which are in the form of white and gray.
- The gray metal changes its color to white at temperatures of above 13.2 °C and very rapidly above 100 °C. This metal has about 10 naturally occurring isotopes with different mass numbers.
Health Effects of Tin
- Tin in organic form is most dangerous to the 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.
