NEET Chemistry Atomic Radius Assertion Reason Question
Assertion (A): The atomic radius of a cation is smaller than its parent atom. | Reason (R): The removal of an electron from an atom results in a decrease in effective nuclear charge.
Both A and R are true, and R is the correct explanation of A.
Both A and R are true, but R is not the correct explanation of A.
A is true, but R is false.
A is false.
Correct Answer
Detailed Explanation
While the atomic radius of a cation is indeed smaller than its parent atom, this is due to the same nuclear charge acting on fewer electrons, not a decrease in effective nuclear charge.
