AB has NaCl type structure. If the radius of the cation A is 90 pm, then the radius of the anion will be

3 Answers

Ans given :: 217.4 pm by taking radius ratio 0.414.

Isn't the radii ratio =0.525 in NaCl structure?

NaCl type crystal radius ratio is 0.414..in NaCl crystal there is some distortion coz the radius ratio > 0.414

Bhai, lekin jab NaCl type lattice bola hai, toh wahi ratio use karenge naa...
