To solve the question regarding the formula unit of Na₂O and the coordination number ratio, we can follow these steps: ### Step 1: Identify the Structure of Na₂O Na₂O has an anti-fluoride structure. In this structure, the oxide ions (O²⁻) occupy the face-centered cubic (FCC) lattice. **Hint:** Remember that in an FCC lattice, the oxide ions are located at specific lattice points. ### Step 2: Determine the Number of O²⁻ Ions in the Unit Cell ...
