2. Copper Report
Copper comes from a Latin term cyprium (after the island of Cyprus) meaning "the metal of Cyprus." Copper dates back to prehistoric times but has been mined for 5000 years, however it's exact discoverer is unknown. Cu is Copper's chemical symbol. It contains 29 protons/electrons (atomic number) and 35 neutrons. It's atomic weight is 65.39. Copper i
3. Aluminum
was the first discovered by Danish chemist Christan Oersted in 1825 using a chemical process involving potassium amalgam. The process was later improved by French chemist Friedrich Wohler by using metallic potassium. Woholer was also the first person to measure the specific gravity of . Pure is found in an ore called bauxite. IT is estimated that i
4. Magnesium, Beryllium, And Calcium
The lightest metal of all the elements is magnesium. It is the most abundant element in the Earths crust. Since it is so abundant, the aerospace industry uses it extensively. Magnesium is not a strong element by itself. Alloys have been developed to improve magnesiums hardness, resistance against corrosion, and its ability to be welded. These all
