Which of the following ions has the smallest radius? — Periodic Table and Periodicity Chemistry Question

💡 Solution & Explanation

I'd be happy to help, but I need to see the answer choices (A, B, C, D) to explain why C is the smallest ion. Could you please provide the four ion options? Once you do, I'll explain: 1. **The trend**: How ionic radius changes with atomic number (across a period and down a group) 2. **Charge effect**: How increased positive charge decreases radius 3. **Why C is correct**: Compare the specific ions given Please share the options and I'll give you a complete solution.
