Model of crystal structure, copper and aluminum
Ball and wire model on wood base. Cubic structure labeled copper 9-aluminum 4. Balls painted black, blue, lavender, gray, yellow, orange, red; base painted white. Unit cell size given as 8.685 Å.
Ball and wire models show the relative positions of the centers of the component atoms in a representative volume element of a crystal. The sizes of the balls have no significance; the actual atoms in most structures are in fairly close contact. The scale of most models is approximately 1 inch = 1 Å.
