WebIonic radii of cation A + and anion B - are 102 and 181 pm respectively. These ions are allowed to crystallize into an ionic solid. This crystal has cubic close packing for B -. A + is present in all octahedral voids. The edge length of the unit cell of the crystal AB is 566 pm. Explanation: a = 2 (r + + r -) a = 2 (102 + 181) a = 566 pm Web4 sep. 2024 · September 4, 2024 by Alexander Johnson. The ionic radius is half the distance between atomic ions in a crystal lattice. To find the value, ions are treated as if … bea baumann
