# Problem: For metallic structures, does the packing efficiency (see Sample Exercise 12.1 in textbook) increase or decrease as the number of nearest neighbors (the coordination number) decreases?

###### FREE Expert Solution

We are asked if the packing efficiency of metallic structures increases or decreases as the number of nearest neighbors (the coordination number) decreases.

Recall that the packing efficiency is the fraction of volume in a crystal structure that is occupied by constituent particles (volume of space occupied by the spheres/total volume).

This means that:
