Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A): Atomic radius of gallium is higher than that of aluminium.
Reason (R): The presence of additional d-electrons offer poor screening effect for the outer electrons from increased nuclear charge.
In the light of the above statements, choose the most appropriate answer from the options given below:
- (A) is correct but (R) is not correct
- (A) is not correct but (R) is correct
- Both (A) and (R) are correct and (R) is the correct explanation of (A)
- Both (A) and (R) are correct but (R) is not the correct explanation of (A)
Answer
(C) Both (A) and (R) are correct and (R) is the correct explanation of (A)
