Some of the properties of crystalline solids depend on the crystal structure<\/strong><\/a> of the material and how atoms, ions, or molecules are spatially arranged. A crystal lattice<\/strong> is a repeating pattern of mathematical points that extends throughout space, and the forces of chemical bonding<\/a> cause this repetition. This repeated pattern controls properties like strength<\/strong>, ductility<\/strong>, density<\/strong><\/a>, conductivity<\/strong><\/a> (property of conducting or transmitting heat, electricity, etc.), and shape<\/strong>. There are 14 general types of such patterns known as Bravais lattices<\/strong>. Three relatively simple crystal structures are found for most of the common metals.<\/p>\n

Face-centered Cubic<\/h2>\n

In a face-centered cubic (fcc) arrangement of atoms, the unit cell consists of eight atoms at the corners of a cube and one atom at the center of each of the faces of the cube. In an fcc arrangement, a unit cell contains (8 corner atoms \u00d7 \u215b) + (6 face atoms \u00d7 \u00bd) = 4 atoms. This structure, along with its hexagonal relative (hcp), has the most efficient packing (74%). Metals containing FCC structures include austenite, aluminum, copper, lead, silver, gold, nickel, platinum, and thorium, and these metals possess low strength and high ductility.<\/p>\n<\/div><\/div>\n
