Use foam balls and toothpicks to create a space-filling model of a simple cubic unit cell. The surfaces of the balls should be touching. On the cube above, draw a cut- away view showing only the atoms (or parts of atoms) inside one unit cell. Pay particular attention to where atoms touch (or not). One atom has been drawn in for you as an example. Number of atoms per unit cell - Coordination number (number of nearest neighbors)- Co A...

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...

The atoms of crystalline solid pack together into a
three-dimensional array of many small repeating units called
unit cells. The simplest of the unit cells are those that
have cubic symmetry, with atoms positioned at the corners of a
cube. Atoms can also be found in the sides (faces) of the cube, or
centered within the body of the cube. It is important to realize
that a unit cell is surrounded by other unit cells in every
direction. Therefore, face...
