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...

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...

Q. 3. Potassium fluoride adopts the rock salt (NaCl type) structure, with a density of 2.48 g/cm3. Using the data for the Part 4 model you constructed, calculate the expected distance between the center of the potassium ion and the center of an adjacent fluoride ion in pm. Q. 4. The diameter of a Cs+ ion is 334 pm; the diameter of a Br- ion is 392 pm. For CsBr, which crystallizes in the CsCl type structure from Part 5,...

Answer question 23-25
The unit cell for HCP is not a cube. This structure is made by placing one flat layer of a close packed hexagon arrangement of seven spheres on top of the holes in another layer, a third layer directly above first layer, and so on. This layering is referred to as A,B,A,B. Hold the model up to the light and note the tunnels that pass straight through the structure. See the figure below. 23. What is the...
