    Study Notes

    Body Centered Cubic Lattice

    • A body-centered cubic (BCC) lattice consists of identical atoms with a radius of R.
    • In a BCC lattice, each unit cell has a total of 2 atoms: 8 atoms at the corners of the cube (each shared by 8 adjacent cells) and 1 atom at the center of the cube.

    Number of Atoms per Unit Cell

    • There are 2 atoms per unit cell in a BCC lattice.

    Coordination Number

    • The coordination number of a BCC lattice is 8, meaning each atom is in contact with 8 nearest neighboring atoms.

    Packing Factor

    • The packing factor (PF) of a BCC lattice is 0.68, which is the ratio of the volume occupied by the atoms to the total volume of the unit cell.
    • PF = (Volume of atoms) / (Volume of unit cell) = (2 × (4/3) × π × R³) / (2 × R³) = 0.68
