Question

All possible lattice types are observed in the

• A. cubic crystal system
• B. monoclinic crystal system
• C. tetragonal crystal system
• D. orthorhombic crystal system

Answer 1

The Correct Option is D

The question asks which crystal system exhibits all possible lattice types. The correct answer is the orthorhombic crystal system.

In crystallography, a lattice system is a class of point groups and space groups that have similar symmetry. Crystals are classified into seven lattice systems: cubic, tetragonal, orthorhombic, monoclinic, triclinic, hexagonal, and rhombohedral.

Each crystal system can have various types of Bravais lattices. Here's a breakdown:

• Cubic Crystal System: Contains simple cubic, body-centered cubic, and face-centered cubic lattices.
• Monoclinic Crystal System: Comprises two lattices - simple monoclinic and base-centered (also called end-centered) monoclinic.
• Tetragonal Crystal System: Includes simple tetragonal and body-centered tetragonal lattices.
• Orthorhombic Crystal System: This system contains the most diverse range with four lattice types - simple orthorhombic, base-centered orthorhombic, body-centered orthorhombic, and face-centered orthorhombic.

Therefore, the orthorhombic crystal system is the only one that encompasses all possible lattice types available within that system, making it unique in its diversity.

In conclusion, the orthorhombic crystal system includes all possible lattice types: simple, base-centered, body-centered, and face-centered. This feature distinguishes it from all other crystal systems.
