Assertion : Atomic radius of Ga is larger than that of aluminium Reaso

1.	Assertion : Atomic radius of Ga is larger than that of aluminium Reason : Atomic radius always increases down the groups.
Answer» Correct Answer - D There are deviations in properties of elements of a group in p-block Atomic radius of Ga is less than that al Al because of the presence of additional 10 d-electrons which offer poor screening effect for the outer electrons from the increased nuclear charge in gallium.
