The correct Answer is:
To solve the question regarding the size comparison between tetrahedral voids (T-void) and octahedral voids (O-void) in the closest packing of atoms, we can follow these steps: ### Step 1: Understand the Definitions - **Tetrahedral Void (T-void)**: This void is formed when four atoms are arranged in a tetrahedral geometry around a central void. In a close-packed structure, a tetrahedral void is located between two layers of atoms. - **Octahedral Void (O-void)**: This void is formed when six atoms are arranged in an octahedral geometry around a central void. An octahedral void is found between two layers of atoms, with one atom above and one atom below the plane of the void. ### Step 2: Visualize the Structures - Draw or visualize the arrangement of atoms in a close-packed structure (like FCC or HCP). - Identify the positions of tetrahedral and octahedral voids within this arrangement. ### Step 3: Compare the Sizes - The tetrahedral void is smaller than the octahedral void due to the arrangement of surrounding atoms. - The tetrahedral void is surrounded by four atoms, while the octahedral void is surrounded by six atoms, leading to a larger size. ### Step 4: Conclusion - Based on the comparison, we conclude that the size of the octahedral void is greater than that of the tetrahedral void. ### Final Answer - The correct option is **B**: The size of the octahedral void is greater than that of the tetrahedral void. ---
