c. BODY CENTERED CUBIC LATTICE (BCC)
15. Create a space filling drawing of the atoms in the lattice structure for the two planes indicated: (hand draw an embed an image)
16. What is the length of one internal diagonal, in terms of r?
17. Determine the # of spheres in one unit cell.
18. What is the coordination number?
19. Calculate the percent of the bcc unit cell which is occupied, showing all work. The calculation of the edge length, in terms of r, requires quite a bit of trigonometry.
