PASS/wishing you success in your studies
Crystalline Solids - Atoms or ions of a solid arranged in a pattern repeating itself in three
dimensions, they have a crystal structure referred to as a crystalline solid.
ex. Metal, alloys, ceramics
Unit Cell -
Lattice Parameter -
Coordinate Number - The number of atoms that are connected to the central atom in to
neighbor unit cell.
Density - p = (n * A) / (V_c * N_a)
Atomic Packing Factor (APF) - Is the fraction of space occupied by atoms.
Simple Cubic Structure:
[Example], APF=?, CN=?, a=? - [Example], APF=?, CN=?, a=?
Face Centered Cubic (FCC):
[Example], APF=?, CN=?, a=? - [Copper, Aluminum, Gold, Silver], APF=0.74, CN=12,
a=2R√2
