Question

Stable ceramic crystal structures form when anions that surround a cation are all in direct contact with the cation, and the coordination of that cation is related to the cation-anion radius ratio. a. Given an ionic radius for Na+ ion = 0.95Å and for Cl- = 1.81Å, what is the cation to anion radius ratio for NaCl? b. Referring to the range of radius ratios to coordination numbers (in Callister), what is the coordination number of the Na+ ions in the NaCl structure?

Step 1

Given ionic radius for Na+ ion = 0.95Å and for Cl- = 1.81Å. Cation to anion radius ratio = 0.95Å / 1.81Å ≈ 0.524 Show more…
