How many atoms in a primitive unit cell
WebEach atoms is shared by three neighbors in the the same layer and with another hexagonal prism on top or below. So they count as 2 × 6 × 1 3 × 1 2 = 2 atoms. The total count thus is 6. These diagrams of the hexagonal closest packing, do not represent the the unit cell as the most simple unit from which the crystal is build by symmetry ... WebMar 8, 2016 · And there are 6 atoms in the middle layer of hexagonal prism, however 3 of those atoms have a larger section of their volumes inside the HCP Unit Cell, where as other 3 atoms have a smaller section ( Complete volume of their spheres - The "larger" section of their volumes ).
