please i need help with all questions
5. List the following cubic packing structures from least (1) to most (3) efficient structures (in terms of "packing efficiency"; be sure you can also sketch out the face and packing of these cubic structures, as well as calculate the packing efficiency of each one yourself. Do not simply memorize the packing efficiency values!) a. Simple Cubic b. Body-centered cubic c. Face-centered cubic 6. Calculate the mass of a single unit cell of...

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...
How many atoms are in the following unit cells? Body centered cubic, face centered cubic (FCC), a hypothetical body centered/face centered cubic crystal, and a hypothetical diamond cubic structure with superimposed face centered cubic and body centered cubic atoms. Calculate the ratio of the packing factors for the following cases: simple cubic to face centered cubic. simple cubic to hypothetical face centered body centered cubic crystal (i.e. a face centered cubic with a similar atom placed in the center simple...

If an iron stom has a radius of 126 pm, what is the distance between lattice points at two opposite comer of the unit cell) rs of the unit cell? (Note: a line drawn between the points would go through the center a. /2(126 pm)-178 pm b. 2(126 pm) 252 pm C. 2(126 pm) 109 pm d. 4(126 pm)-504 pm e3126 pm)-218 pm...
