The purpose of this report and lab was to assist in visualizing the structure of infinitesimally small objects and how they fit together. Normal object fit together similarly to microscopic atoms and experiment 2 exploits this to help understand structure property relationships. The knowledge gained here directly applies to the world as applications of the materials becomes apparent as the properties are explored.
Copper There are a plethora of modern technological uses of copper. It can be used in electrical wiring, building sturdy structures, transportation and sculptures. Based off data gathered from the internet [1]. Copper is used 65% of the time for electrical infrastructure, 25% for construction

Zinc has been used to create reliable alloys since 500 BC [4]. These alloys included brass (copper + zinc) and supplemented bronze (copper + zinc + tin). So what gives zinc this amazing property to alloy usefully with other metals? Simply put, electron structure. Pure zinc is a unfavorable material to use, it has a low toughness and is generally brittle with a strength less than steal. These properties make it unusable in most modern mechanical processes. The structure of zinc (HCP) is caused by the electron structure of zinc the HCP is the lowest energy that the zinc atoms can arrange themselves in to. The brittleness of zinc is caused by its hexagonal close packing, the lattice structure fails to create dislocations. Instead of bending (like copper) it shatters because the stress could not be relieved. During the 3D crystal experiment the HCP arrangement was one of the structures that was explored. It was interesting that 2 different arrangements; hexagonal close packing and cubic close packing contain the same number of atoms. A notable fact about zinc is that life on earth depends on zinc to survive, it is used in more than 300 enzymes. Zinc deficiency was accepted as a clinical health problem in 1961
