  1. Define a primitive unit cell.

    A primitive unit cell has constituent particles (atoms, ions, or molecules) located only at its corners.

  2. Define a centered unit cell.

    A centered unit cell has constituent particles at its corners, and also at one or more other positions within the cell or on its faces.

Part c

A centered unit cell is a unit cell in a crystal lattice where, in addition to the particles at the corners, there are also particles located at other specific positions, such as the center of the unit cell or the centers of its faces.

Part d

Two types of centered unit cells are:

  1. Body-centered cubic (BCC)
  2. Face-centered cubic (FCC)
