Question

Assertion (A) Noble gases are highly reactive.
Reason (R) Noble gases have stable outer electronic configuration.

• A. Both $A$ and $R$ are correct; $R$ is the correct explanation of $A$.
• B. Both $A$ and $R$ are correct; and $R$ is not the correct explanation of $A$.
• C. $A$ is correct; $R$ is incorrect.
• D. $R$ is correct; $A$ is incorrect.

Answer 1

Answer: (D)

Noble gases are very less reactive due to stable outer electronic configuration like $n s^{2} n p^{6}$ or $n s^{2}$.
Thus, $R$ is correct but $A$ is incorrect.
