Metallic beryllium has a hexagonal close-packed structure and a density of 1.85 g/cm3. Assume beryllium atoms to be spheres of radius r. Because beryllium has a close-packed structure, 74.1% of the space is occupied by atoms. Calculate the volume of each atom, then find the atomic radius, r. The volume of a sphere is equal to 4πr3/3.
