To determine the maximum and minimum sizes of the anions filling the voids in an `AB`-type solid with NaCl structure, we can follow these steps: ### Step 1: Identify the given data - The radius of the cation (R+) is given as 75 pm. ### Step 2: Understand the structure - In an `AB`-type solid with NaCl structure, the cations are packed in a face-centered cubic (FCC) arrangement, and the anions occupy the octahedral voids. ...
