The ion with smallest radius among the following is
- A \(\mathrm{Ca}^{2+}\)
- B \(\mathrm{K}^{+}\)
- C \(\mathrm{Ti}^{4+}\)
- D \(\mathrm{Sc}^{3+}\)
Answer & Solution
Correct Answer
(C) \(\mathrm{Ti}^{4+}\)
Step-by-step Solution
Detailed explanation
All the given species have the elements belonging to the same period and ionic radii decrease in a period from left to right. \(\mathrm{Ti}^{4+}\) lies to the right of the other species and would be even more small due to a greater positive charge. Thus, order of radii would be…
