If the close-packed cations in an `AB`-type solid gave a radius of `75` pm. What would be the maximum and minimum sizes of the anions filling the voids?

(a) If the close packed cations in an AB type solid have a radius of 75 pm, what would be the maximum and minimum sizes of the anions filling the voids ? (b) Br^(-) ions form a close packed structure. If the radius of Br^(-) ion is 195 pm, calculate the radius of the cation that just fits into the tetrahedral hole. Can a cation A^(+) having a radius of 82 pm be slipped into the octahedral hole of the crystal A^(+)Br^(-) ?

If the close-packed cations in an AB -type solid with NaCl structure have a radius of 75 pm. What would be the maximum and minimum sizes of the anions filling the voids?

A solid A^(+)B^(-) has NaCl -type close-packed structure. If the anion has a radius of 250 pm, what should be the ideal radius for the cation? Can a cation C^(+) having radius of 180 pm be slipped into the tetrahedral site of the crystal A^(+)B^(-) ? Give reason for your answer.

A solid A^(+)B^(-) has NaCl -type close-packed structure. If the anion has a radius of 250 pm, what should be the ideal radius for the cation? Can a cation C^(+) having radius of 180 pm be slipped into the tetrahedral site of the crystal A^(+)B^(-) ? Give reason for your answer.

A solid A^(o+)B^(ɵ) has NaCl -type close-packed structure. If the anion has a radius of 250 pm, what should be the ideal radius for the cation? Can a cation C^(o+) having radius of 180 pm be slipped into the tetrahedral site of the crystal A^(o+)B^(ɵ) ? Give reason for your answer.
