Aluminum is pronounced as ah-LOO-men-em. History and Uses: Although aluminum is the most abundant metal in the earth's crust, it is never found free in nature. All of the earth's aluminum has combined with other elements to form compounds.Two of the most common compounds are alum, such as potassium aluminum sulfate (KAl(SO 4) 2 Â·12H 2 O), and aluminum oxide (Al 2 O 3).About 8.2% of the earth's crust is composed of aluminum.istory and Uses: Although aluminum is the most abundant metal in the earth's crust, it is never found free in nature.

Â· just now. The formula for aluminium chloride is AlCl3. This is because aluminium is a 3rd family element, and thus has 3 valence electrons. chlorine is a 7th family element and thus has 7 valence electrons. When molecules form, generally they form to get 0 or 8 valence electrons. So, aluminium gives 3 electrons to the chlorine atoms and goes to 0, and each chlorine atom gets 1, bringing each to 8.
