In comparison to the parent atom, the size of the — Periodic Table and Periodicity Chemistry Question

💡 Solution & Explanation

I notice the question appears incomplete — it cuts off at "the size of the" without specifying what is being compared (anion, cation, ion, etc.) or providing answer options. **To provide an accurate solution, please clarify:** 1. What is being compared to the parent atom? (e.g., anion, cation, specific ion) 2. What are the answer options (A, B, C, D)? **General principles for size comparisons:** - **Anions** are **larger** than parent atoms (added electrons increase repulsion, expand electron cloud) - **Cations** are **smaller** than parent atoms (lost electrons → less repulsion, nuclear charge pulls remaining electrons closer) - The more electrons added/removed, the greater the size change Once you provide the complete question and options, I can explain why option A is correct and why others are wrong.
