1) (5 points) Walter prepares blue Side-centered cubic (scc) cell crystals, named as myth, which adopt a side-centered cubic (scc) cell, where atoms occupy the center of sides of a cubic cell. (The myth molecule is assumed to have a perfect spherical shape.) a) Find-out hew many atoms 3 re -1 Calculate the atomic packing ferctor (APE) of scc unit cell. c) Giventres the radius (initi) of myth-molecue. Determine the number of holes with coordination numbers 6,8 , and 12 per unit cell
