Which of the following radii has the smallest value for the same element?
Cationic Radius
Covalent Radius
Metallic Radius
Van der Waal's Radius
Cationic Radius has the smallest value for the same element.
And the order of radii-
Cationic Radius < Covalent Radius < Metallic Radius < Van der Waal's Radius
Therefore, Option(1) is correct.
