What is the sum of cationic and anionic radius in a crystal lattice is equal to?
Correct answer: B. Inter ionic distance R
- A. Inter-titian distance R
- B. Inter ionic distance R
- C. Inter cationic distance R +
- D. Inter-anionic distance R-
Explanation
The answer is B. Interionic distance for any ionic compound determines the extent of attraction of anions and cations. Therefore the sum of cationic and anionic radius gets equal to interionic distance.

About Crystal Lattice
A crystal lattice is the regular three-dimensional arrangement of particles in a crystalline solid. The content includes lattice points, unit cells, coordination number, packing patterns, and the differences among ionic, metallic, molecular and covalent network crystals, which should not be confused with amorphous solids.
