To determine the coordination number of each ion in the given crystals, we will analyze each compound step by step. ### Step 1: NaCl - In NaCl, sodium ions (Na⁺) and chloride ions (Cl⁻) are arranged in a face-centered cubic (FCC) lattice. - Each Na⁺ ion is surrounded by 6 Cl⁻ ions, and each Cl⁻ ion is surrounded by 6 Na⁺ ions. - **Coordination number of Na⁺ = 6** - **Coordination number of Cl⁻ = 6** ...
