Aliminium in nature
Aluminium is naturally highly reactive, which means we practically only meet its compounds in nature.
Aluminium is the third most represented element in the earth’s crust. According to the latest figures, aluminium makes us 7,5 - 8,3% of the earth’s crust.
Its concentration is very low in seawater, totalling around a mere 0,01 mg Al/l.
In space, there is a ratio of 1 atom of aluminium to half a million atoms of hydrogen.
