Options

A. four
B. three
C. two
D. one

Answer

To determine the number of space lattices present in the triclinic system, we can follow these steps:

### Step 1: Understand the Triclinic System
The triclinic system is one of the seven crystal systems in crystallography. In this system, the unit cell parameters are defined as follows:
- The lengths of the axes are unequal: \( a \neq b \neq c \)
- The angles between the axes are also unequal: \( \alpha \neq \beta \neq \gamma \)
- None of the angles are 90 degrees: \( \alpha, \beta, \gamma \neq 90^\circ \)

### Step 2: Identify the Space Lattices
A space lattice is a three-dimensional arrangement of points that represent the positions of atoms, ions, or molecules in a crystal. The triclinic system has only one type of lattice arrangement due to its unique parameters.

### Step 3: Count the Number of Space Lattices
In crystallography, the number of distinct space lattices (or Bravais lattices) in the triclinic system is one. This is because all the parameters are unequal and there are no restrictions that would allow for more than one unique arrangement.

### Conclusion
Thus, the number of space lattices present in the triclinic system is **1**.
