Physical properties of Diamond and graphite!!!
Answers
• Diamond has a very high density
(3.51 g cm- ³) due to its unique structure.
•Diamond is a bad conducter of electricity .This is, due to the fact that all the four valence electrons are used in bond formation and no free electron is available.
•Because of very high refractive index (2.5) ,Diamond has high shine and brilliance.
Graphite...
•Graphite has low density.
• Graphite has very -very low high melting point due to the presence of strong single covalent bonds in graphite structure.
• Graphite is soft having slippery touch. This is due to its structure in which one layer of carbon atoms can slide over other layers....
Hope this will help you...
Diamond: Diamond is a crystalline form of Carbon; Which is found in purest and hardest state of matter. Diamond is a brilliant and Hard substance. Diamond is tetragonal shaped because of it's carbon structure. Each carbon on diamond is attached to it's neighboring 3 carbon atoms, this makes the diamond Tetra shaped.
Property of Diamond:
i) Density of Diamond is 3.5g/cm^3
ii) Melting point of diamond is 3500 degree Celsius.
iii) There is no effect of Acids and bases on diamond.
iv) Diamond doesn't dissolve in any solvent.
v) Diamond is bad conductor of electricity; As it does not have free electrons.
vi) When diamond is heated at 800 degree Celsius in presence of oxygen, then only it released the CO2.
Uses of Diamond:
i) Diamond is used in ornaments and decoration.
ii) Diamond is used for Glass cutting and rock drilling machines.
iii) Diamond is used in making eye surgery knives.
iv) Diamond dust is used for polishing of other diamonds.
v) Diamonds is used in Space-crafts and Satellites to prevent radiations.
