❓Frequently Asked Questions 🔍
❓ Q1. What is the Radius Ratio Rule?
👉 It is a rule in solid-state chemistry that predicts the coordination number of an ionic compound based on the ratio of ionic radii.
❓ Q2. Why is the radius ratio important?
👉 It determines whether ions can pack stably without causing lattice collapse.
❓ Q3. Is the radius ratio rule always accurate?
👉 No. It assumes hard-sphere ions and works best for highly ionic compounds.
❓ Q4. Who should use this calculator?
👉 Chemistry students, educators, materials scientists, and researchers.
❓ Q5. Can it predict real crystal structures?
👉 It provides a theoretical prediction, not an experimental confirmation.
