<h1>
Aluminium is a chemical element in the boron group with symbol Al and
atomic number 13. It is a silvery-white, soft, nonmagnetic, ductile
metal. Aluminium is the third most abundant element (after oxygen and
silicon), and the most abundant metal in the Earth's crust. It makes up
about 8% by weight of the Earth's solid surface. Aluminium metal is so
chemically reactive that native specimens are rare and limited to
extreme reducing environments. Instead, it is found combined in over 270
different minerals. The chief ore of aluminium is bauxite.
