How many atoms in hcp
WebSep 25, 2024 · how to calculate the number of atoms in a hexagonal unit cell 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.
