    Figure 3.1.15. A final look at cubic close-packing.

    Note that this cube has an atom in the center of each face; hence the name, face-centered cubic.

    • A cubic close-packed takes the name "cubic" from the presence of a cubic unit cell.
    • This cubic unit cell is oriented diagonally to the close-packed layers.
    • This cubic unit cell has an atom in the center of each face; it is also called "face-centered cubic".
