Question

explain a unit cell as a building block of crystalline solids

Answer 1

hello friend...here u go...
>>>>>If the atoms or molecules are uniquely arranged in crystalline solid or liquid we call it as a crystal structure. ... This periodicity is due to the arrangement of atoms/molecules in the latticepoints. The crystal structure as a whole can be considered as the repetition of unit .....hope this will help anyway

Answer 2

Explanation:

Crystalline solids are anisotropic in nature, that is, some of their physical properties like electrical resistance or refractive index show different values when measured along different directions in the same crystals. This arises from different arrangement of particles in different directions.
