For crystal structures that contain only one kind of atom, the nearest neighbors of each atom can be visualized as lying along a line of the unit cell. For a body-centered cubic structure what is the orientation of that line with respect to the unit cell and how many atomic radii does it contain?
a. cell edge and 2 atomic radii
b. face diagonal and 4 atomic radii
c. body diagonal and 3 atomic radii
d. face diagonal and 2 atomic radii
e. body diagonal and 4 atomic radii
