Question

a) Give a few examples of metals that crystallize in fcc lattices.

b) Draw an fcc unit cell.Draw it clearly so that the three coordinate axes and the location of the atoms can be seen. c) Is there an atom in the center of an fcc unit cell?d) What is the coordination number of the atoms in an fcc lattice?

e) How many atoms are contained in the fcc unit cell?f) What is the atomic packing factor in an fcc unit cellin comparison to an hcp unit cell? (No calculation required, looking up the packing factor from the book or web is ok here.)How does the atomic packing differ between an fcc unit cell and an hcp unit cell?Explain using a sketch of layer stacking.
