1. Is there a difference in packing (coordination number) between these two types (FCC and HCP) of structures?
2. Look at the two structures. A small difference in arrangement of atoms causes a dramatic difference in the properties of FCC ductile metals and HCP brittle metals. Can you see it? Try to draw the differences (You can draw the 3-layers separately):
