Crystalline part of otherwise amorphous solids are known as:
Correct answer: B. Crystallites
- A. Allotrope
- B. Crystallites
- C. Isomorph
- D. Polymorph
Explanation
Option B is correct.The crystalline parts of otherwise amorphous solids are known as crystallites.Crystallites are small regions of a solid that have a regular atomic arrangement.They are typically found in amorphous solids,which are solids that do not have a regular atomic arrangement.The presence of crystallites in an amorphous solid gives the solid some of the properties of a crystalline solid,such as a higher melting point and a more ordered structure.

About Crystalline Solids
Crystalline solids contain particles arranged in a regular repeating lattice described by a unit cell. Their study includes coordination number, packing efficiency, density, anisotropy, cleavage, polymorphism and common crystal systems, along with ionic, molecular, covalent network and metallic crystals. Crystalline order differs from the random arrangement of amorphous solids.
