The atomicity of which among the following is the maximum?

Options

A. helium
B. fluorine
C. ozone
D. sulphur

Explanation

To determine the atomicity of the given options and identify which has the maximum atomicity, we will follow these steps:

### Step-by-Step Solution:

1. **Understand Atomicity**:
- Atomicity refers to the number of atoms present in a molecule of an element or compound.
- It can be classified as:
- Monoatomic: 1 atom (e.g., Helium - He)
- Diatomic: 2 atoms (e.g., Fluorine - F2)
- Polyatomic: More than 2 atoms (e.g., Ozone - O3)

2. **Analyze Each Option**:
- **Option 1: Helium (He)**
- Helium is a noble gas and exists as a single atom.
- Therefore, its atomicity = 1 (Monoatomic).

- **Option 2: Fluorine (F2)**
- Fluorine exists as a diatomic molecule (F2).
- Therefore, its atomicity = 2 (Diatomic).

- **Option 3: Ozone (O3)**
- Ozone is a triatomic molecule consisting of three oxygen atoms.
- Therefore, its atomicity = 3 (Polyatomic).

- **Option 4: Sulfur (S8)**
- Sulfur exists as a molecule with eight sulfur atoms arranged in a crown shape.
- Therefore, its atomicity = 8 (Polyatomic).

3. **Compare the Atomicities**:
- Helium: 1
- Fluorine: 2
- Ozone: 3
- Sulfur: 8

4. **Identify the Maximum Atomicity**:
- Among the options analyzed, sulfur (S8) has the highest atomicity of 8.

### Conclusion:
The element with the maximum atomicity among the given options is **Sulfur (S8)**.
