Why are these voids called tetrahedral voids?

Options

  1. ABecause they are square in shape
  2. BBecause they are hexagonal in shape
  3. CBecause a tetrahedron is formed when the centres of four spheres surrounding the void are joined
  4. DBecause they are octahedral in shape

Correct answer

C. Because a tetrahedron is formed when the centres of four spheres surrounding the void are joined

Step-by-step solution

These voids are called tetrahedral voids because a tetrahedron is formed when the centres of the four spheres surrounding the void are joined, as mentioned in the paragraph.
