Physical Properties: silvery white colour, solid, ductile, metal, light weight/low density (2.702 g/cm3), non-magnetic, malleable, opaque, conductor

Chemical Properties: does not react with air (does not rust), does not react with water, burns with oxygen creating a brilliant white flame

Hans Christian Ørsted.

A pure form of the metal was first successfully extracted from ore in 1825 by Danish chemist Hans-Christian.

CATION-----Aluminum is a mental amply found in the earth's crust, and never found in element form. The two compounds found most often are aluminum sulphate and aluminum oxide. It then becomes a cation because it transferred its elections onto another element.

has three valence electrons and wants to lose them to get eight electrons. It is easier to lose three electrons, than gain 5 electrons

Tin cans and pop cans

Transportation (aircraft, trucks, railway cars, bicycles)

Aluminum foil-food and beverage containers resistant to corrosion

Window frames

Kitchen utensils

Atomic Size -one of the smaller elements because it has 3 energy levels and 3 electrons on the last shell, where as the max energy levels are 7.

- Atomic radius: 118pm

- As the atomic number increases along each row of the periodic table, the additional electrons go into the same outermost shell, causing the atomic radius to decrease due to the increasing nuclear charge.

Ionization: -larger energy required therefore harder to remove an electron (also why when bonded it is the cation) - the ionization energy increases from left to right in the periods and up the groups. - Aluminum is the first element of its period with electrons in the 3p shells makes the first ionization energy comparably low to the other elements in the same period, because it only has to get rid of one electron to make a stable 3s shell, the new valence electron shell Electron Affinity: -fairly large amount of energy given off so it is reactive - Aluminum Affinity -- 42.5kJ/mol

Other Info

1887: Austrian engineer Karl Josef Bayer developed a chemical process where alumina can be extracted from an common naturally occurring aluminum ore.

- still used today to produce almost total world’s aluminum.

- Aluminum is found in the ground and the ore miner is called bauxite

Crystal Structure: Cubic

Density @ 293 K: 2.702 g/cm3

Aluminum is present in more than 270 minerals, and is the third most abundant metal found after oxygen and silicon

Almost never found in nature because high likelihood of binding with oxygen

Australia is the leading producer of the worlds alunimum
