Questions asked by users might not always be phrased in the clearest way.
Identify the ion that has the smallest ionic radius. rn1. Cl^-rn2. S^2-rn3. Al^3+rn4. Na^+
Accepted Answer
Of the given ions, Na+ has the smallest ionic radius. This is because Na+ has lost an electron to achieve a stable electron configuration, resulting in a smaller atomic radius. The other ions have either gained electrons or lost multiple electrons, which results in a larger ionic radius compared to Na+.
