Which of the following crystal system has four types of unit cells?
Options
- ACubic
- BOrthorhombic
- CTetragonal
- DMonoclinic
Correct answer
B. Orthorhombic
Step-by-step solution
The seven crystal systems and the number of Bravais lattices they possess are as follows: Cubic: 3 (Primitive, Body-centered, Face-centered) Tetragonal: 2 (Primitive, Body-centered) Orthorhombic: 4 (Primitive, Body-centered, Face-centered, End-centered) Hexagonal: 1 (Primitive) Rhombohedral: 1 (Primitive) Monoclinic: 2 (Primitive, End-centered) Triclinic: 1 (Primitive) The orthorhombic crystal system is the only one that has all four types of unit cells. Answer: Orthorhombic
