A face-centered cubic unit cell structure consists of atoms arranged in a cube where each corner of the cube has a fraction of an atom with six additional full atoms positioned at the center of each cube face. The atoms at the corner of the cube are shared with eight other unit cells.

Which crystals have face-centered cubic lattice?

Copper, silver (Ag), and gold (Au) crystallize in fcc lattices. In the hcp and the fcc structures the spheres fill 74 percent of the volume, which represents the closest possible packing of spheres. Each atom has 12 neighbours.

Which of the following metals has face-centered cubic structure?

Metals that possess face-centered cubic structure include copper, aluminum, silver, and gold.
