Unformatted text preview: Halite Sylvite Diamond Quartz 2) Given the following ionic radii, calculate the radius ratios and coordination numbers for the following pairs of ions. What type of coordination polyhedron would form around each cation? What is the value of the evb for each bond in the coordination polyhedra? Ionic Radii: C = 0.26 Å Na =1.16 Å Ca = 1.14 Å P = 0.52 Å Al = 0.68 Å O = 1.26 Å Cl = 1.81 Å F = 1.19 Å Ion Pairs: (1) C 4+ – O 2-(2) Na +- Cl-(3) Ca 2+- F-(4) P 5+- O 2-...
