Determine the density of each cube. The less dense cube is the amorphous solid.
It is also important to note that many crystals are made from more than one kind of atom. For example, proteins will form crystals under the right conditions, and proteins are more complex than a single metal atom. The unit cell concept applies to protein crystals as it does to single atoms. The unit cell may contain one or more proteins and weigh thousands of atomic mass units. Since it is in the form of a crystal, one of the unit cells will enable you to recreate the entire protein crystal. This fact is exploited when structural biologists perform X-ray crystallography to determine the atomic structures of proteins.

You are a researcher for a golf club manufacturer. You are given two identical looking cubes of a metal alloy. You are informed that they are made of the exact same material, but one is crystalline, whereas the other is amorphous. It is your job to determine which one is amorphous this one is more stress-resistant and is useful in reinforcing golf clubs. Which of the following is the best way to determine which is which? a. Determine the density...
Rank the crystal lattice structures in order of decreasing efficiency of space in the structure. Rank from most to least efficient use of space -hexagonal close packing -face-centered cubic -body-centered cubic -simple cubic
Rank the crystal lattice structures in order of decreasingefficiency of space in the structure. 1.Simple cubic 2.Body centered cubic 3.Face centered cubic 4.Hexegonal close packed I know simple cubic is the least effcient, and i figured itwhould be HCP-FCC-BCC-Simple cubic, but its not.. help please!! thanks
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...
EENG 245 Physical electronics HW 1 1) The NaCl crystal is cubic, and can be described as follows. Na atoms sit at the corners and faces of a cube, and Cl atoms sit in between two Na atoms. This means that a Clatom is found half-way along each of the cube edges, and there is a Cl in the center of the cube. (We could also have described the lattice by interchanging Na and Cl in the description above.) Another...
