The correct Answer is:
To arrange the types of arrangement in terms of decreasing packing efficiency, we need to analyze the packing efficiencies of different crystal structures. Here’s a step-by-step solution: ### Step 1: Identify the Types of Arrangement The types of arrangements we need to consider are: - Simple Cubic (SC) - Body-Centered Cubic (BCC) - Hexagonal Close Packing (HCP) - Cubic Close Packing (CCP) ### Step 2: Determine the Packing Efficiency of Each Arrangement Next, we need to know the packing efficiency for each of these arrangements: - **HCP and CCP**: Both have a packing efficiency of **74%**. - **BCC**: Has a packing efficiency of **68%**. - **Simple Cubic (SC)**: Has a packing efficiency of **54%**. ### Step 3: Arrange in Decreasing Order Now that we have the packing efficiencies, we can arrange them in decreasing order: 1. HCP and CCP (74%) 2. BCC (68%) 3. Simple Cubic (54%) ### Final Arrangement Thus, the final arrangement in terms of decreasing packing efficiency is: - HCP / CCP (highest) - BCC - Simple Cubic (lowest) ### Conclusion The correct order of packing efficiency from highest to lowest is: **HCP = CCP > BCC > Simple Cubic**
