Chemistry - Solid State Question with Solution | TestHub

Crystalline solids have a regular and periodic arrangement of constituent particles.

They have a sharp and definite melting point.

Due to the ordered arrangement of particles, crystalline solids are anisotropic in nature, meaning their physical properties like refractive index, electrical resistance, etc., have different magnitudes when measured along different directions.

Amorphous solids are isotropic. Therefore, the statement that a crystalline solid is isotropic is incorrect.

Answer: It is isotropic.
