Aluminium aluminum in american and canadian english is a chemical element with the symbol al and atomic number 13.It is a silvery-white, soft, non-magnetic and ductile metal in the boron group.By mass, aluminium makes up about 8 of the earths crust it is the third most abundant element after oxygen and silicon and the most abundant metal in the crust, though it is less common in the.

Great quantities of lead, both as the metal and as the dioxide, are used in storage batteries.Lead is also used for cable covering, plumbing, and ammunition.The metal is very effective as a sound absorber, is used as a radiation shield around x-ray equipment and nuclear reactors, and is used to absorb vibration.

The elements in group 13 are also capable of forming stable compounds with the halogens, usually with the formula mx3 where m is a boron-group element and x is a halogen.18 fluorine, the first halogen, is able to form stable compounds with every element that has been tested except neon and helium, 19 and the boron group is no exception.It is even hypothesized that nihonium could form.
