Tin:

Atomic number

50

Symbol

Sn

Atomic weight

118.69

Discovery

Known since ancient time

Electronic configuration

[Kr]5S24d105p2

Word origin

Anglo-Saxon tin, Latin sternum both names for elements 

Melting point

231.96810C

Boiling point

22700C

Specific gravity

5.75 (gray) or 7.31 (white)

Electrical resistivity

11.5 Micro ohm cm

 Properties:

1.      This is a malleable silvery metal which takes a high polish.

2.      It possesses a highly crystalline structure and is moderately ductile.

3.      Its conductivity is poor.

4.      Its tensile strength is low.

5.      Tin is resistant to attack by sea, distilled, or soft tap water, but it will corrode in strong acids, alkalis and acid salts. The presence of oxygen in a solution accelerators the rate of corrosion.

6.      It can be drawn into wires.

Uses: Tin is used to coot other metals to present corrosion. Tin plate over steel is used to make cans for food. Tin salts may be sprayed onto glass to produce electrically conductive coatings. Molten tin is used to float molten glass to produce window glass. It is used to enamel porcelain, cable sheathing and tubes.

Sources: The primary source of tin is cassiterite. Tin is obtained by reducing its ore with coal in a reverberatory furnace.
