[Kr]5S24d105p2
Word origin
Anglo-Saxon tin, Latin sternum both names for elements
Melting point
231.96810C
Boiling point
22700C
Specific gravity

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.
The number of independent directions in which a system (or gas molecule) can have motion, are called as the number of degrees of freedom of that molecule or object. The number of d

why we use compensater??
write all equationes of projectile motion used in calculation of vertical and horizontal motion
How is that circuit wont be broken even there is an air gap in between the parallel plates? Ans) In AC circuit capacitor offers resistance to current as aresistor would do in DC.
