Chemistry Copper/Diamond/Graphite Question! 10 Easy Points!?
Help please!
Copper has a cubic close-packed structure. Why does copper wire not break when it is bent?
Diamond is used as an abrasive on cutting tools. How do you explain this property in terms of the structure of diamond? List one common property of diamond.
Graphite is used as a lubricant. How do you explain this property in terms of the structure of graphite? What is one common property of graphite?
Thanks so much! 10 points for the best answer!!
Copper doesn't break because of it's structure (holes in the center) and metals are soft therefore easier to bend. Molecules slide on each other.
Diamonds have the most tightly packed structure ,a hexagonal structure. Diamonds are the hardest gem on the Mohr scale. (hardness scale for gems)
Graphite is soft and therefore can be bended.
Graphite is a good electrical conductor.

Can someone pleaseeee help me with this?
The element copper has ccp packing with a face-centered cubic unit cell. The density of Cu is 8920 kg/m3. Calculate the volume (mL) of the unit cell of copper.
density = mass/volume
FCC = 4 atoms in one unit cell
mass of 1 copper atom = 63.546 therefore mass of 4 C atom = 254.184
volume = mass/density
= 0.0284959641255605 meter cube
= 28.4959641255605 liters
= 28495.9641255605 milliliters
