To determine the maximum and minimum sizes of the anions filling the voids in an `AB`-type solid where the radius of the cations is given as `75 pm`, we will use the radius ratio concept from solid-state chemistry. ### Step-by-Step Solution: 1. **Understand the Radius Ratio**: The radius ratio (r+) / (r-) for ionic solids helps us determine the size of the anions relative to the cations. For an `AB`-type solid, the radius ratio ranges are: - Minimum radius ratio (for stable packing): 0.414 - Maximum radius ratio (for stable packing): 0.732 ...

NaCl is a AB type of solid . Its crystalline structure is known as rock salt structure in which r_"Na"^+ and r_"Cl"^- are 95 and 181 pm respectively , where Cl^- is present at the lattice point of face centered cubic unit cell Na^+ ions are located in void and those compounds which have same crystalline structure also have same coordination system in which Na^+ and Cl^- ions are surrounded by certain number of opposite ions respectively.
