A solid AB has NaCl structure. If the radius of cation A^(+) is 170 pm

1.	A solid AB has NaCl structure. If the radius of cation A^(+) is 170 pm, calculate the maximum possibleradius of the anionB^(-)
Answer» Solution :The FORMULA ` r_(+) = 0.414 xx r_(-)` GIVES maximum possible radius of ANION for a given CATION, for close packing
