Question

The number of lattice arrangements in different crystal systems are:

• A. 8
• B. 7
• C. 9
• D. 14

Answer 1

Answer: (B)

7

Answer 2

There are seven different types of lattice systems
1. Cubic (e.g., $NaCl$ )
2. Monoclinic (e.g., $\left.CaSO _{4} \cdot 2 H _{2} O \right)$
3. Orthorhombic (e.g., $MgSO _{4} \cdot 7 H _{2} O$ )
4. Rhombohedral (e.g., $CaCO _{3}$ )
5. Tetragonal (e.g., $\left.TiO _{2}\right)$
6. Triclinic (e.g., $\left.K _{2} Cr _{2} O _{7}\right)$
7. Hexagonal (e.g., $\left.SiO _{2}\right)$
