What is the coordination number of a particle in hcp structure?

Options

  1. A2
  2. B4
  3. C6
  4. D12

Correct answer

D. 12

Step-by-step solution

In hcp structures, each sphere is surrounded by 12 neighbouring spheres, 6 in its own layer, 3 above and 3 below. Hence, the coordination number of any sphere in hep structure is 12.
