Question

Define crystal lattice and unit cell​

Answer 1

Answer:

In crystallography, crystal structure is a description of the ordered arrangement of atoms, ions or molecules in a crystalline material. The unit cell is defined as the smallest repeating unit having the full symmetry of the crystal structure. The geometry of the unit cell is defined as a parallelepiped, providing six lattice parameters taken as the lengths of the cell edges (a, b, c) and the angles between them (α, β, γ).

Answer 2

Answer:

Crystal lattice :-

The symmetrical three-dimensional arrangement of atoms inside a crystal.

Unit cell:

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.
