What is minimum number of spheres required to develop a tetrahedral void?
- A 2
- B 4
- C 6
- D 3
Answer & Solution
Correct Answer
(B) 4
Step-by-step Solution
Detailed explanation
A tetrahedral void is a type of interstitial space formed in a close-packed arrangement of spheres. In order to create a tetrahedral void, four spheres are required. The void is formed between these four spheres and the surrounding spheres in a tetrahedral geometry.
- In a close-packed structure like FCC (Face-Centered Cubic) or HCP (Hexagonal Close-Packed), a tetrahedral void is formed when one sphere is surrounded by four others, and the void is the empty space at the center of this arrangement.
Thus, 4 spheres are the minimum number required to create a tetrahedral void.
