The element Aluminum can be found on the periodic table.  It is the most abundant metal that can found in earth's crust.  Because it is such a reactive metal it is often found combined with additional minerals.  It has been used in combination with other materials and minerals in order to make it useable for many different things.

Aluminum is a light weight silver colour metal with chemical symbol 'Al'.In periodic table it appears in the group of 'other metals'.

It is the third most common element after oxygen and silicon. Also it is the most plentiful metal in earth's crust.

Some properties of pure aluminium are given below.

Atomic number ... 13

Atomic weight  ... 26.9815

Density      ... .... 2.7 g/cc

Melting point   ... 660.2 degrees C

Aluminium has very good strength to weight and strength to electrical conductivity. This makes aluminium suitable for many application in engineering, construction and electrical industry applications.

The chemical formula for Aluminum is Al. This can be found on the periodic table of elements. Also on the periodic table of elements, the atomic number and the atomic mass can be seen. Aluminum is a light weight silvery metal. The charge of an aluminum ion is +3 because it has 3 valence electrons, meaning 3 electrons must be removed in order to satisfy the octet rule of noble gases. Losing 3 electrons will mean that the ion will have a positive charge of three.
