The correct Answer is:
To analyze the given assertion and reason, we can break down the solution into the following steps: ### Step 1: Understand the Assertion The assertion states that "atoms of each element are stable and emit characteristic spectrum." - **Explanation**: Each element has a unique atomic structure, which leads to stability in its atoms. When these atoms are excited (for example, by heat or electricity), they emit light at specific wavelengths, resulting in a characteristic spectrum. ### Step 2: Understand the Reason The reason states that "the spectrum provides useful information about the atomic structure." - **Explanation**: The emitted spectrum consists of distinct lines (known as spectral lines) that correspond to specific energy transitions of electrons within the atom. By analyzing these lines, we can infer details about the atomic structure, such as energy levels and electron configurations. ### Step 3: Analyze the Relationship Now we need to determine if the reason correctly explains the assertion. - **Analysis**: While both the assertion and the reason are true, the reason does not directly explain why atoms are stable and emit a characteristic spectrum. The stability of atoms is due to the balance of forces within the atom and the arrangement of electrons, while the spectrum is a result of electron transitions. ### Step 4: Conclusion Based on the analysis: - The assertion is true: Atoms of each element are stable and emit a characteristic spectrum. - The reason is true: The spectrum does provide useful information about atomic structure. - However, the reason is not the correct explanation for the assertion. Thus, the final answer is: **Both assertion and reason are true, but the reason is not the correct explanation of the assertion.** ---
