What is the coordination number in both cubic close-packed (ccp) and hexagonal close-packed (hcp) structures?

Options

  1. A4
  2. B6
  3. C8
  4. D12

Correct answer

D. 12

Step-by-step solution

The coordination number in both cubic close-packed (ccp) and hexagonal close-packed (hcp) structures is 12, as each sphere is in contact with twelve spheres.
