Aluminium (or aluminum in North American English) is a chemical element; it has symbol Al and atomic number 13. Aluminium has a density lower than that of other common metals, about one-third that of steel. It has a great affinity towards oxygen, forming a protective layer of oxide on the surface when exposed to air.
The spelling aluminium is the international standard in the sciences according to the IUPAC recommendations. Humphry Davy, the element's discoverer, first proposed the name alumium, and then later aluminum. The name aluminium was finally adopted to conform with the -ium ending of some metallic elements. [105]
He then juxtaposes aluminium to alloy by saying that the aluminium has a lower melting point which will leave the other metals in the alloy as solid dross."as much aluminium as dross, and as much dross as alloy" thus implying that aluminium is not an alloy, but will come from it when it separates from the alloy and leaves dross behind.)
