Gold (Au) has a FCC structure and its atoms are arranged more closely together than
those in chromium (Cr) which has a BCC structure. Give two (2) differences between
these two metals due to their crystal structures.
2. Niobium has an atomic radius of 0.1430 nm and a density of 8.57 g/cm³.
Determine whether it has an FCC or BCC crystal structure.
3. the iron has crystal lattice type (BCC) at (910°c) degrees
Celsius and becomes (FCC) above this temperature. If we
assume that the radius of the atom is constant in both
cases, what is the percentage of iron density in both cases?
