Imagine a unit cell that consists of corner-centered atoms "A", body-centered atom "B", face-centered atoms "C", and edge-centered atoms "D". This would mean that the total parts of "A" would add to Blank 1 atom(s), the total parts of "B" would add to Blank 2 atom(s), the total parts of "C" would add to Blank 3 atom(s), and the total parts of "D" would add to Blank 4 atom(s). Assume that a crystal structure is made up...
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...
