Atomicity of sulphur is:

Options

A. 8
B. 4
C. 2
D. 1

Explanation

To determine the atomicity of sulfur, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of Atomicity**:
- Atomicity refers to the number of atoms in a molecule of an element. For example, in the case of oxygen (O2), the atomicity is 2 because it consists of two oxygen atoms.

2. **Identify the Molecular Form of Sulfur**:
- Sulfur primarily exists in a molecular form as S8. This means that a molecule of sulfur is made up of 8 sulfur atoms.

3. **Count the Number of Atoms in the Molecular Form**:
- Since the molecular form of sulfur is S8, we count the number of sulfur atoms in this molecule. There are 8 sulfur atoms in S8.

4. **Conclude the Atomicity of Sulfur**:
- Therefore, the atomicity of sulfur, which is the number of atoms in the form in which it exists (S8), is 8.

### Final Answer:
The atomicity of sulfur is 8.
