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. b. What is the volume of one unit cell in 3 ? Enter a number. 3 c. Assuming that the atoms are spheres and the radius of each sphere is 1.73 , what is the
