Match the picture to the type of cubic unit cell and rank the unit cells in their relative packing  efficiency. Cell Name Packing Efficiency 2. –/5 points 1/3 submissions Notes The mark will be displayed after 1 submissions. Question part 1 2 3 4 5 In modeling solid-state structures, atoms and ions are most often modeled as spheres. A structure built using spheres will have some empty, or void, space in it. A measure of void space in a particular structure is the packing efficiency , defined as the volume occupied by the spheres divided by the total volume of the structure. Given that a solid crystallizes in a face centered cubic structure that is 4.89 on each side, please answer questions a - e. (1 = 1 x 10 -10 m) a. How many atoms are there in each unit cell? Enter a number.
