What is minimum number of spheres required to develop a tetrahedral void?

Options

  1. A2
  2. B4
  3. C6
  4. D3

Correct answer

B. 4

Step-by-step solution

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 a
