Metallic Mg has a hexagonal close-packed structure and a density of 1. – InterviewSolution

1.	Metallic Mg has a hexagonal close-packed structure and a density of 1.74 g/cc. Assume Mg atoms to be spheres with radius r. Because Mg has a close-packed structure, 74.1% of the space is occupied by atoms. Calculate the volume of each atom and then find the atomic radius r.
