Each point in the catalyst lattice is known as :

Options

A. Lattice point
B. lattice dot
C. Lattice shape
D. Lattice origin

Answer

To solve the question "Each point in the catalyst lattice is known as:", we need to analyze the options provided and understand the terminology related to crystal lattices.

### Step-by-Step Solution:

1. **Understanding the Concept of a Lattice**:
- A lattice in chemistry refers to a regular arrangement of points in space, which represents the positions of atoms, ions, or molecules in a crystal structure.

2. **Identifying the Points in a Lattice**:
- In a crystal lattice, each point corresponds to the position of an atom, ion, or molecule. These points are crucial for understanding the structure and properties of the material.

3. **Defining the Term**:
- The term used to describe each point in the lattice is specifically known as a "lattice point." This is a standard term used in crystallography and materials science.

4. **Evaluating the Options**:
- Option A: Lattice Point - This is the correct term.
- Option B: Lattice Dot - This is not a standard term used in this context.
- Option C: Lattice Shape - This refers to the overall geometry of the lattice, not individual points.
- Option D: Lattice Origin - This refers to a specific point of reference in the lattice, not each point.

5. **Conclusion**:
- Based on the definitions and the analysis of the options, the correct answer to the question is **Option A: Lattice Point**.

### Final Answer:
Each point in the catalyst lattice is known as **lattice point**.
