Question

Quizplus · Accepted Answer

Face-centered cubic lattices have a packing efficiency of 74%, which is higher than the 52.4% packing efficiency of simple cubic lattices. Copper adopts a face-centered cubic structure, while polonium adopts a simple cubic structure, indicating that the packing efficiency of copper is higher than that of polonium.
