AI Generated Solution

To determine the coordination number of \( \text{Na}^+ \) ions in relation to \( \text{Cl}^- \) ions, we can use the radius ratio rule. Here’s the step-by-step solution: ### Step 1: Identify the radii of the ions - The radius of \( \text{Na}^+ \) is given as 95 pm. - The radius of \( \text{Cl}^- \) is given as 181 pm. ### Step 2: Calculate the radius ratio To find the radius ratio, we use the formula: ...
