WebIn a face-centered cubic crystal, each atom has 12 nearest neighbors (NN). That’s the theoretical maximum number of NNs possible–each of those NNs contributes a bond, giving the crystal structure very high stability. FCC has 6 next-nearest neighbors, and 24 next-next nearest neighbors. Face-Centered Cubic Lattice Constants WebAug 14, 2024 · Each corner atom is shared with eight adjacent unit cells and so a single unit cell can claim only 1/8 of each of the eight corner atoms. Similarly, each of the six atoms centered on a face is only half-owned by the cell. The grand total is then (8 × 1/8) + (6 × ½) = 4 atoms per unit cell. Interstitial Void Spaces
