This bar chart shows the distribution of crystal structures among solid elements at standard conditions. Most elements crystallize in one of a few common arrangements.

Face-centered cubic (FCC) and body-centered cubic (BCC) dominate among metals, offering efficient atomic packing. Hexagonal close-packed (HCP) is common for elements like titanium, zinc, and rare earths. The structure affects material properties: FCC metals (copper, aluminum, gold) are ductile; BCC metals (iron, tungsten, chromium) are stronger but less workable.
