Text Solution

AI Generated Solution

To solve the question regarding the percentage of unoccupied spaces in BCC (Body-Centered Cubic) and FCC (Face-Centered Cubic) arrangements, we need to understand the concept of packing efficiency. ### Step-by-Step Solution: 1. **Understand Packing Efficiency**: - Packing efficiency is defined as the percentage of the total space occupied by particles in a crystal structure. - The remaining space in the structure is considered unoccupied. ...
