Aluminum metal crystallizes in a cubic close-packed structure (face-centered cubic cell
Chapter 11, Problem 11.62(choose chapter or problem)
Aluminum metal crystallizes in a cubic close-packed structure (face-centered cubic cell, Figure 11.34). (a) How many aluminum atoms are in a unit cell? (b) What is the coordination number of each aluminum atom? (c) Assume that the aluminum atoms can be represented as spheres, as shown in the drawing for Exercise 11.61. If each AI atom has a radius of 1.43 A, what is the length of a side of the unit cell? (d) Calculate the density of aluminum metaL
