In a compound, oxide ions are arranged in `ccp`. One-sixth of the tetrahedral voids are occupied by cations. `(A)` and one-third of `OV_(s)` are occupieed by cations `(B)`. (a) What is the formula of the compound of the compound? (b) What are the charges on `A` and `B` ?

Text Solution

AI Generated Solution

To solve the problem, we need to determine the formula of the compound and the charges on the cations A and B based on the arrangement of oxide ions and the occupancy of the voids. ### Step-by-Step Solution: **Step 1: Identify the arrangement of oxide ions.** - The oxide ions (O²⁻) are arranged in a close-packed structure, specifically a cubic close-packed (ccp) arrangement. **Step 2: Determine the number of oxide ions.** ...
