A small building block which belongs to whole information about crystal structure is called?
Correct answer: B. Unit Cell
- A. Cell
- B. Unit Cell
- C. Crystal lattice
- D. Crystal unit
Explanation
A unit cell is the smallest repeating unit of a crystal lattice that contains all the information about the crystal's structure. It is a three dimensional parallelepiped (a box-like shape) with defined edges and angles. The arrangement of unit cells forms the crystal lattice.

About Crystal Lattice
A crystal lattice is the regular three-dimensional arrangement of particles in a crystalline solid. The content includes lattice points, unit cells, coordination number, packing patterns, and the differences among ionic, metallic, molecular and covalent network crystals, which should not be confused with amorphous solids.
