The correct Answer is:
To solve the question regarding the positions of cesium ions in the crystal lattice of cesium chloride (CsCl), we can follow these steps: ### Step 1: Understand the Structure of CsCl In the crystal lattice of cesium chloride, the arrangement of ions is crucial. CsCl has a specific type of crystal structure known as the body-centered cubic (BCC) structure. **Hint:** Recall that CsCl consists of two types of ions: Cs⁺ and Cl⁻. Understanding their arrangement is key. ### Step 2: Identify the Radius Ratio The radius ratio of the cation (Cs⁺) to the anion (Cl⁻) plays an important role in determining the type of lattice structure. For CsCl, the radius ratio falls between 0.734 and 1. **Hint:** Remember that the radius ratio can help predict the coordination number and the type of lattice structure. ### Step 3: Determine the Positions of Ions In the CsCl lattice: - The Cl⁻ ions occupy the corners of the cubic unit cell. - The Cs⁺ ions are located at the body center of the unit cell. **Hint:** Visualize the cubic unit cell and remember where each type of ion is placed. ### Step 4: Conclude the Position of Cs⁺ Ions Since the Cs⁺ ions are located at the body center of the unit cell, we can conclude that the correct answer to the question is that Cs⁺ ions are present at the body center of the unit cell. **Hint:** Think about how the arrangement of ions affects the overall structure and stability of the crystal. ### Final Answer In the crystal lattice of CsCl, Cs⁺ ions are present at the **body center of the unit cell**.
