The figures given below show the location of atoms in three crystallographic planes in a FCC lattice. Draw the unit cell for the corresponding structures and identify these planes in your diagram. |

Dear student,
The conventional face-centered cubic (FCC) lattice. This structure is very common amongst metallic elements because it maximises nearest neighbor interactions (coordination number of 12). The unit cell has a packing efficiency of 0.74. The FCC structure is also known as the cubic close-packed (CCP) structure.
