2. Face-centered cubic (FCC)
 FCC (face centered cubic): Atoms are
arranged at the corners and center of each
cube face of the cell.

3. Face-centered cubic (FCC)

4. BCC: Body Centered Cubic
 Atoms are arranged at the corners of the
cube with another atom at the cube center.

5. BCC: Body Centered Cubic
 Close Packed Plane cuts the unit cube in
half diagonally
 2 atoms in one unit cell

6. Hexagonal Close Packed (HCP)
 Cell of an HCP lattice is visualized as a top
and bottom plane of 7 atoms, forming a
regular hexagon around a central atom. In
between these planes is a half-hexagon of 3
atoms.
 • There are two lattice parameters in HCP, a
and c, representing the basal and height
parameters respectively.
