Question

Assertion: All the reactive elements occur in the combined state in nature.

Reason: The compounds of reactive metals are more stable than the metals themselves.

विकल्प

• If both Assertion and Reason are CORRECT and Reason is the CORRECT explanation of the Assertion.

• If both Assertion and Reason are CORRECT but Reason is not the CORRECT explanation of the Assertion.

• If Assertion is CORRECT but Reason is INCORRECT.

• If Assertion is INCORRECT but Reason is CORRECT.

Answer 1

If both Assertion and Reason are CORRECT and Reason is the CORRECT explanation of the Assertion.

Explanation:

All the reactive elements occur in a combined state in nature because their compounds are more stable than the metals themselves. Hence, reactive metals like sodium, potassium, and calcium and reactive non-metals like fluorine, chlorine, and bromine are found as compounds, not in free form. This is because these metal compounds possess greater stability compared to the pure reactive metals, which readily react with other substances to form compounds. Therefore, the reason correctly explains the assertion.
