प्रश्न
How will you distinguish between the following pairs of terms : Crystal lattice and unit cell
उत्तर
Crystal lattice and unit cell:
| Crystal lattice | Unit cell |
|
The crystal lattice can be defined as a symmetrical three-dimensional arrangement of atoms inside a crystal.
|
The unit cell can be defined as the smallest three dimensional portion of a complete space lattice which when repeated over and again in different directions produces the complete space lattice is called the unit cell. Or The unit cell can be also be defined as the smallest group of atoms which has the overall symmetry of a crystal, and from which the entire lattice can be built up by repetition in three dimensions. |
