Ionic radii of cation A + and anion 
are 102 and 181 pm respectively. These ions are allowed to crystallize into an ionic solid. This crystal has cubic close packing for 
. A + is present in all octahedral voids. The edge length of the unit cell of the crystal AB is_____pm. (Nearest Integer)
Text Solution
Verified by ExpertsThe correct answer is:
566
(566)
a = 2(r + + r - )
a= 2 (102 +181)
a = 2(283)
a = 566 pm
