Select whether the statement is true or false. The atomicity of phosphorus is four.

Answer

To determine whether the statement "The atomicity of phosphorus is four" is true or false, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of Atomicity**:
- Atomicity refers to the number of atoms present in a molecule of a substance.

2. **Identify the Form of Phosphorus**:
- Phosphorus exists in a molecular form as P₄ in nature. This means that each molecule of phosphorus is made up of four phosphorus atoms.

3. **Calculate the Atomicity of Phosphorus**:
- Since phosphorus exists as P₄, the atomicity of phosphorus is 4 (because there are 4 atoms in one molecule of P₄).

4. **Evaluate the Statement**:
- The statement claims that "The atomicity of phosphorus is four." Based on our understanding and calculation, this statement is indeed correct.

5. **Conclusion**:
- Therefore, the statement is true.

### Final Answer:
The statement "The atomicity of phosphorus is four" is **True**.
