... looked at as having packing planes. These are planes in which the molecules are stacked amongst each other. Objectives: This experiment was conducted to construct and observe the three main packing systems FCC, BCC, and HCP structures. This will give a visual representation of the packing planes and allow a better understanding as to how these different molecular arrangements affect the physical properties of the materials they make up.e Procedure To conduct the lab 50 - 60 cork balls and stands were obtained from the teacher. Using the cork balls and stand the crystalline structures were constructed based on reference from texts. Using these arrangements fiv3e questions were answered. The orientation of the FCC structure was then manipulated to represent its close packed plane and compared it with HCP. Observation Questions: 1. Given the silver has a face centered cubic structure, and an atomic radius of 1.44x10-10m, determine the density of silver show ...
