    Which of the following has largest atomic radii?

    A) \[Al\]                                    

    B) \[A{{l}^{+}}\]

    C) \[A{{l}^{2+}}\]                                  

    D) \[A{{l}^{3+}}\]

    Correct Answer: A

    Solution :

                     Atomic radii varies inversely with nuclear charge, ie, \[Atomic\text{ }radii\propto \frac{1}{nuclear\text{ }ch\arg e}\] Hence, Al shows the largest atomic radii.
