WebApr 5, 2024 · Using this notion, the FCC unit cell structure has a total of four atoms: six halves on each face and eight one-eighth atoms at the corners. (4 atoms) = (1/2 atoms x 6 faces) + (1/8 atoms x 8 corners) The face-centred cubic (fcc) has a coordination number of 12 and a unit cell size of 4 atoms. Note: WebAug 14, 2024 · How many atoms are contained in a unit cell? 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.
