WebHence, the total number of atoms in a unit cell = 4 atoms Thus, in a face-centred cubic unit cell, we have: 8 corners × 1/8 per corner atom = 8 × 1/8 = 1 atom 6 face-centred atoms × 1/2 atom per unit cell = 3 atoms Therefore, the total number of atoms in a unit cell = 4 atoms. Volume of HCP Unit Cell WebHCP has 6 atoms per unit cell, lattice constant a = 2r and c = (4√6r)/3 (or c/a ratio = 1.633), coordination number CN = 12, and Atomic Packing Factor APF = 74%. HCP is a close-packed structure with AB-AB stacking. Don’t worry, I’ll explain what those numbers mean and why they’re important later in the article.
