WebA primitive cubic, body-centred cubic (BCC), or face-centred cubic unit cell can be used (FCC). We’ll go through the three different sorts of unit cells in this section, and also, we’ll learn about the number of atoms per unit cell in a cubic unit cell. Unit Cells: Determining the Unit Cell of a Crystal WebThe unit cell of body centred cube has 1 atom at each of the eight corners and 1 atom of the centre of the body. Thus, the atom at the centre remains in contact with 8 corners atoms. Hence, co-ordination number of bcc is 8.
