Ozone is alan

Options

A. element
B. mixture
C. allotrope
D. None of these

Answer

To solve the question "Ozone is:", we will analyze the options provided and determine the correct classification of ozone.

### Step-by-Step Solution:

1. **Understanding the Definition of Ozone**:
- Ozone is a molecule composed of three oxygen atoms. Its chemical formula is O₃.

2. **Analyzing the Options**:
- **Option A: Element** - An element is a pure substance that cannot be broken down into simpler substances by chemical means. While ozone is made of oxygen atoms, it is not a single type of atom; it is a molecule.
- **Option B: Mixture** - A mixture consists of two or more substances that are not chemically combined. Ozone is not a mixture; it is a specific compound made of three oxygen atoms.
- **Option C: Allotrope** - Allotropes are different forms of the same element in the same physical state. Since ozone (O₃) is a different form of oxygen (O₂), it qualifies as an allotrope of oxygen.
- **Option D: None of these** - This option is incorrect because we have identified ozone as an allotrope.

3. **Conclusion**:
- Based on the definitions and analysis of the options, the correct answer is **Option C: Allotrope**.

### Final Answer:
Ozone is an allotrope of oxygen (Option C).
