Chemistry-Atomic Radius
NEET Chemistry Atomic Radius Assertion Reason Question
Type: Assertion Reason-assertion-Medium-Class 11
Assertion (A): The atomic radius of an anion is larger than its parent atom. | Reason (R): Anions have more electrons, leading to increased electron-electron repulsion and decreased effective nuclear charge.
A
Both (A) and (R) are true and (R) is the correct explanation of (A).
B
Both (A) and (R) are true but (R) is not the correct explanation of (A).
C
(A) is true but (R) is false.
