Aluminum

Aluminum has a low density of 2.7, which means low weight.

Aluminum boils at 4,566 degrees Fahrenheit and 2,519 degrees Celcius.Aluminum melts at 1,221 degrees Fahrenheit and 660.3 degrees Celcius.

Aluminum is a Chemical Element discovered in the year 1825 by Hans Christian Orsted in Denmark.

Atomic number is 13. Atomic weight is 26.98. SYmbol is Al. Post_Transition metal.

Aluminum is malleable which means it can be flattend into thin sheets.

Physical Properties: Aluminum is a shiny, silvery white colored metal that is light in weight and strong.

Pure aluminum easily forms alloys with many elements such as copper, zinc, magnesium, manganese and silicon.Pure aluminum is a reactive element and is rarely found on Earth in its free form.

Chemical Properties:Aluminum acts as an excellent conductor of electricity and heat, but is non-magnetic. When it is exposed to the air, a thin layer of aluminum oxide is formed on the surface of the metal. This prevents further corrosion and rusting.

Aluminum is the third most abundant element and the most abundant metal found in the Earth's crust. It is generally found on Earth in minerals and compounds such as feldspar, beryl, cryolite, and turquoise.

Interesting Facts about Aluminum:It makes up around 8% of the Earth's crust by weight.Aluminum is 100% recyclable.It has no function in biology.When aluminum reacts with hydrochloric acid, it produces hydrogen gas.In the mid-1800s aluminum was more expensive than gold.An alternative spelling often used for the element is "aluminium".

Because of Aluminums abundance, low cost, and useful qualities, aluminum is used in thousands of products. It is often used as a metal because of its light weight. Applications for aluminum alloys include soda cans, automobile parts, bicycles, aluminum foil, power lines, siding for houses, and even baseball bats.
