NEET Chemistry Periodic Table Assertion Reason Question
Assertion (A): Noble gases have large positive electron gain enthalpies.
Reason (R): Noble gases can easily attain stable electronic configurations by gaining an electron.
Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A).
Both Assertion (A) and Reason (R) are true but Reason (R) is not the correct explanation of Assertion (A).
Assertion (A) is true but Reason (R) is false.
Assertion (A) is false but Reason (R) is true.
Correct Answer
Detailed Explanation
Noble gases have large positive electron gain enthalpies because adding an electron would lead to an unstable configuration, not because they easily attain stability.
