Atomicity of Phosphorous is

Options

A. 1
B. 2
C. 4
D. 6

Explanation

To determine the atomicity of phosphorus, we need to understand the concept of atomicity and the molecular formula of phosphorus.

### Step-by-Step Solution:

1. **Understand Atomicity**:
- Atomicity refers to the number of atoms present in a molecule of an element. It indicates how many atoms combine to form a single molecule.

2. **Identify the Molecular Formula of Phosphorus**:
- The molecular formula for phosphorus is \( P_4 \). This means that one molecule of phosphorus consists of four phosphorus atoms.

3. **Determine the Atomicity**:
- Since the molecular formula of phosphorus is \( P_4 \), the atomicity of phosphorus is 4. This indicates that there are 4 atoms of phosphorus in one molecule of phosphorus.

### Final Answer:
The atomicity of phosphorus is 4.
