I don't think it was particularly discovered. Scientists had suspected something unknown in alum as early as 1787. Hans Christian Oersted was the first to produce tiny amounts of it.
Humphry Davy in 1808 identified the existense of a metal base of alum, which he at first termed alumium and later aluminum.

While H.C. Oersted actually didn't discover aluminum but was the first person to isolate the element aluminum. He did this via using reduction on aluminum chloride.
No but it is made of aluminum which is the most prevalent element in the earth.
Cutting aluminum foil in half is a physical change. A physical change alters the form of a substance without changing its chemical composition. In this case, the aluminum foil remains aluminum foil after being cut in half, just in two smaller pieces. No new substances are formed during this process, so it is considered a physical change.
Under IUPAC naming conventions, AlCl3 is called aluminum chloride. It is also commonly called aluminum trichloride and aluminum (III) chloride.
The formula (symbol) for aluminum is Al. The symbol for phosphorous is P. The formula for aluminum combined with phosphorous is AlP (aluminum phosphide).
