Compare your result to the actual density of 8.96 g/cm3 for copper. 14. Web"Let us compare BCC and FCC here. At high temperatures, both of these have mobile dislocations, and thus they can sustain large plastic deformations without undergoing fracture. At low temperatures however, while dislocations in BCC are no longer mobile, dislocations in FCC can still move very quickly. new vegas nothin but a hound dog

They offer good wear resistance and can be strengthened through heat treatment.

As a rule, since atoms in a solid attract each other, the more tightly packed arrangements of atoms tend to be more common. (Loosely packed arrangements do occur, though, for example if the orbital hybridization demands certain bond angles.) Accordingly, the primitive cubic structure, with especially low atomic packing factor, is rare in nature, but is found in polonium.
