Name: AluminumSymbol: (Al)Atomic Number: 13Atomic Mass: 26.981539 amu# of protons:13# of neutrons:14# of electrons:13Combining Capacity: +3Classification: "Other metals" or Boron FamilyPhysical Properties: Shiny, silvery white metal(solid). Melting point of 660.37 °C, boiling point of 2467.0 °C, and density of 2.702 g/cm³ at 293 K.

Discoverer: Hans Christian OerstedDate of Discovery: 1825How it's used: Alloys for building construction, transportation, containers and packaging, electrical power lines, cookware, etc.Places to be found: In the crust of the Earth. Australia is the world's largest producer of aluminum, with a major resource at Weipa, Indonesia, China, and Brazil.

- High electrical conductivity- Non-magnetic- Highly malleable and ductile- Corrosion resistant

History

Chemical Properties

Reaction with water/ airAluminum is covered with thin layer of oxide, preventing from the reaction with water. However aluminum will burn with oxygen to form aluminum oxide.

Aluminum will react violently with the halogens, including flourine, chlorine, iodine, and bromine and forms compounds such as aluminum flouride, aluminum chloride, aluminum iodide, and aluminum bromide.

Extra facts

-People have used aluminum in ancient times for dyeing, tanning, and to stop bleeding. -When it was first discovered, new metal was called alumium, then changed to aluminum.-Aluminum has one-third of density then that of a steel, making it very light and durable.-Aluminum is the most abundant metal in the Earth's crust
