WebNov 26, 2024 · While you can reproduce the lattice with Cl at (0.5,0,0), that would mess up the primitive cell. The second basis point has to be inside the FCC unit. Of the 4 octahedral sides that can be the second basis point (3 of the edge half sites and the body center site), only the body center lies within the primitive unit FCC cell. Hope this helps. WebJul 19, 2024 · Exactly 1/8th of each sphere lies inside the cube. Since there are 8 total atoms and 1/8th of each atom lies inside the cube, the number of equivalent atoms in the unit cell is equal to 1 such that 8 atoms × 1 8 = 1 equivalent atom Cubic Unit Cells There are many types of unit cells. The figure below shows three cubic unit cells.

WebIn crystallography, there is the concept of a unit cell which comprises the space between adjacent lattice points as well as any atoms in that space.
