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
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.
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
