    Unit Cell Calculations Name _____________________________ Unit Cells: The Simplest Repeating Unit in a Crystal The structure of solids can be described as if they were three-dimensional analogs of a piece of wallpaper. Wallpaper has a regular repeating design that extends from one edge to the other. Crystals have a similar repeating design, but in this case the design extends in three dimensions from one edge of the solid to the other. We can unambiguously describe a piece of wallpaper by...
