Aluminum (Al), with atomic number 13 and atomic mass 26.98, is a silvery-white metal and the most abundant element in the Earth's crust. It has a boiling point of 2519°C and a melting point of 660.32°C, with a density of 2.702 g/cm³. Commonly found in a solid state, aluminum is highly reactive and not found in nature in its pure form. It has diverse applications, including aluminum cans, kitchen utensils, and electrical transmission lines. Historically named from "Alumina," aluminum was discovered in 1886 by Hall and Héroult.

History • The name Aluminum was derived form the Latin word Alumina • Hall from the U.S. discovered the element in the same year as Heroulf from France. (1886) • The most common uses for aluminum is for making aluminum cans, kitchen utensils, electrical transmission lines, and aircrafts and rockets.
History cont. • Manufacturers used cold war technology to make little league bats out of aluminum • The original spelling of Aluminum was aluminum. They changed the spelling to Aluminium to conform to the –ium endings of most elements. Many countries, including the United States, still use the original spelling.
