Model of crystal structure, magnesium and nickel
Ball and wire model on wood base. Hexagonal structure labeled magnesium-nickel 2. Balls painted black, silver, orange. Unit cell size given as 4.8 x 15.7 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.
MEDIUM: Metal, wood; FORMAT: Painted; LENGTH: Base 10 x 9.25 in.; height 17.25 in.; QUANTITY: 1 model
