The correct Answer is:
To determine the stable form of element A, we need to analyze the options provided and understand the concept of molecular stability. ### Step-by-Step Solution: 1. **Understanding the Question**: The question asks for the stable form of element A, which is represented by a chemical formula. The options given are A2, A3, and A4. 2. **Identifying Diatomic Molecules**: In chemistry, many elements exist in diatomic forms (two atoms bonded together) when they are in their most stable state. Common examples include O2 (oxygen), N2 (nitrogen), and H2 (hydrogen). 3. **Analyzing the Options**: - **Option A (A2)**: This represents a diatomic molecule. Diatomic molecules are often the most stable forms of elements. - **Option B (A3)**: This represents a triatomic molecule. While some elements can exist in triatomic forms, they are generally less stable than diatomic forms. - **Option C (A4)**: This represents a tetraatomic molecule. Similar to triatomic forms, tetraatomic forms are less common and typically less stable than diatomic forms. 4. **Conclusion**: Given that diatomic molecules are the most stable forms for many elements, the most stable form of A is best represented by the formula A2. 5. **Final Answer**: Therefore, the stable form of A may be represented by the formula **A2**. The answer is **Option B**.
