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. WebThis will form the first layer of the packing model. Draw a diagram of the arrangement of the atoms in the space below. Attach 6 of the balls together with toothpicks to form a triangle with 3 balls at the base. This will form the second layer of the packing model.
