SUMMARY
The coordination numbers for simple cubic (SC), body-centered cubic (BCC), and face-centered cubic (FCC) structures are definitively 6, 8, and 12, respectively. To accurately calculate these numbers, one must consider all nearest atoms across multiple unit cells, not just within a single unit cell. The counting of nearest neighbors should include only those atoms that are at the shortest distance from the selected atom. Visual aids, such as drawings or physical models, are highly recommended for understanding these atomic arrangements.
