Question

For hcp lattice the edge length is equal to_____

Answer 1

4atoms per unit cell

Answer 2

Answer:

For hcp lattice the edge length is equal to 4 atoms per unit and hexagonal closest packed  is number of the 12 and it hold 6 atoms per units.

But in the face centered cubic has corrdination number of 12 and it has 4 atoms in every unit cell.

When the body is in the form of cubic has coordination number of the totally 8 contains 2 atoms. Hope it works well and provide best answer of it.
