The atomic radius of metal crystallizing in fcc structure true is 1.25Ao. Hence the volume occupied by atoms in cell crystal is:
Copper has the fcc crystal structure. Assuming an atomic radius of 130 pm for copper atom (Cu = 63.54):
(1) What is the length of the unit cell of Cu?
(2) What is the volume of the unit cell?
(3) How many atoms belong to the unit cell?
(4) Find the density of Cu?
If an element crystallizes as a simple cube, what is the volume of an element provided its density is 1.5 g/cm3 and atomic mass of the element is 63?
