How many atoms in cubic cells
WebThere would be four atoms per unit cell in a face-centered cubic structure and the density of nickel in this structure would be four times as large. Face-centered cubic structure: The experimental value for the density of nickel is 8.90 g/cm 3 . WebIf you are talking about the HCP crystal structure, the conventional HCP unit cell has 6 atoms, while the primitive HCP unit cell has 2 atoms. I hope that illustrates how a primitive crystal cell can have more than one atom per unit cell, but a primitive Bravais lattice must have only 1 lattice point.
