NaCl and CsF have same geometry because they have the same _ ?
Correct answer: B. Ionic radius ratio
- A. Ionization energy
- B. Ionic radius ratio
- C. Electron affinity
- D. Bond length
Explanation
NaCl and CsF have the same geometry because they have the same ionic radius ratio. The ionic radius ratio is the ratio of the radius of the cation to the radius of the anion in an ionic compound. In both NaCl and CsF, the cation is smaller than the anion, but the ratio of their radii is the same. As a result, both compounds adopt the same crystal structure, which is face-centered cubic. The other properties mentioned, such as ionization energy, electron affinity, and bond length, may be different for NaCl and CsF because they have different cations and anions. However, these properties do not directly affect the geometry of the crystal structure

About Shape of Ionic Crystals
Ionic crystal shape depends on the regular arrangement of oppositely charged ions in a three-dimensional lattice. The topic covers coordination number, radius ratios, lattice geometry and structures such as sodium chloride, caesium chloride and zinc sulfide, which should not be confused with the molecular shapes predicted by VSEPR theory.
