The atomicity of which among the following is the maximum ?

Options

A. Helium
B. Fluorine
C. Ozone
D. Sulphur

Explanation

To determine which substance has the maximum atomicity among the given options, we need to understand what atomicity means. Atomicity refers to the number of atoms present in a molecule of a substance.

Let's analyze the atomicity of each option provided:

1. **Helium (He)**:
- Atomicity = 1 (It is a monoatomic gas)

2. **Fluorine (F₂)**:
- Atomicity = 2 (It is a diatomic molecule)

3. **Ozone (O₃)**:
- Atomicity = 3 (It is a triatomic molecule)

4. **Sulphur (S₈)**:
- Atomicity = 8 (It is a polyatomic molecule with eight atoms)

Now, we compare the atomicities:
- Helium: 1
- Fluorine: 2
- Ozone: 3
- Sulphur: 8

From this comparison, we can see that sulphur has the highest atomicity of 8.

**Final Answer**: The atomicity of sulphur (S₈) is the maximum among the given options.
