5 One cause of failure is the use of defective materials. Metals can have several types of defects, including vacancies, interstitial impurities, and substitution impurities. (See your book!) Nickel adopts a face-centered cubic cell. Accordingly, 4 nickel atoms are present in each unit cell. The mass of a nickel atom is 9.746 x 10-26 kg. The density of nickel is 8.908 g/cm. What is the length of an edge of the unit cell? In words or pictures, briefly describe 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...
