Aluminum has 14 neutrons, 13 electrons and 13 protons. Aluminum is a silvery-white metal. Its density is 2.70 grams per cubic centimeter. Its boiling point is 4,566 degrees Fahrenheit, and its melting point is 1,220.58 degrees Fahrenheit.
Although aluminum is not present in free form in nature, compounds such as bauxite contain this element. The Earth's crust is approximately 8.2 percent aluminum.
In 1825, Hans Oersted produced a small quantity of pure aluminum. In subsequent years, other scientists found new methods to produce larger quantities. In the late 1880s, a new method called the Bayer process made it easier to extract aluminum oxide from bauxite.
Aluminum and its alloys are useful for manufacturing a wide array of products, including cans, aircraft parts, window frames and foil.
