How many atoms in a unit cell

WebThe total number of atoms in a unit cell in a cubic unit cell = 4 atoms. End-centred Cubic Unit Cell In an end-centred cubic unit cell, 8 atoms are located on 8 corners of the cube, and 1 atom each is present on two opposite faces of the cube. Therefore, there are 8 atoms present on 8 corners; each atom contributes 1/8th portion of the cell. WebSpecifically, the conventional unit cell had 2 atoms per cell, and the primitive one has 1 atom per cell. Therefore, the primitive unit cell has half the area of the conventional one. Since the new unit cell has only 1 atom per cell, it is the smallest …
