Q- Distinguish between Face-centered and end-centered unit cells
Answer- The Differences between Face-centered unit cells and end-centered unit cells are given below:
| Face-centered unit cell | End-centered unit cell | |
| 1. | In a Face-centered unit cell, the constituent particles are at the corners and one is at the center of each face. | In an End-centered unit cell, the constituent particles are at the corners and one is at the center of opposite corners. |
| 2. | The face-centered unit cell has 4 faces. | The end-centered unit cell has 2 faces. |
| 3. | They are present only in orthorhombic and cubic crystal systems. | They are present only in monoclinic and orthorhombic crystal systems. |
| 4. | E.g. BaSO4, Cu, Al, Au, and Pt | E.g. Na2SO4. 10H2O and MgSO4.7H2O |

What is End face Centred unit cell?
In an End Centered Unit cell, the atoms are present at the corners and at the alternate face center of the cube.
What is the difference between face Centred cubic and face Centred tetragonal?
The Face Centred cubic has a total of 8 corners with lattice points and 6 lattice points at the face. So, the total is 14 lattice points in it. On the other hand, Face Centred tetragonal does not have a defining symmetry of a single four-fold rotation axis.
