As a solid noble gas, solid xenon is structured as face centered cubic (FCC). This is also known as the CCP, which is the cubic closest packing. This crystal lattice structure is the closest that atoms can be packed into a cube. In the FCC structure, there is one atom at each corner and one atom at each face of the cube. The structure fits four atoms in each lattice cube. Face centered cubic structures are the most dense.
