Question

$A l to the power of 3 plus end exponent$ has a lower ionic radius than $M g to the power of 2 plus end exponent$ because

(a) $M g$ atom has less number of neutrons than $A l$
$A l^{3 +}$ has a higher nuclear charge than $M g^{2 +}$
(c) Their electronegativities are different
$A l$ has a lower ionisation potential than $M g$ atom

The correct answer is: $A l to the power of 3 plus end exponent$ has a higher nuclear charge than $M g to the power of 2 plus end exponent$
