To determine the ionic radii of the lithium ion (Li⁺) and iodide ion (I⁻) in lithium iodide (LiI), which occurs as a cubic closed packing structure, we can follow these steps: ### Step 1: Understand the Structure Lithium iodide (LiI) has a face-centered cubic (FCC) unit cell. In this structure, the iodide ions (I⁻) occupy the corners of the cube, while the lithium ions (Li⁺) are located at the face centers. ### Step 2: Use the Edge Length The edge length of the unit cell is given as \( a = 624 \) pm. ...
