Physical Properties
Density: low, 2700 kg/cubic meter
Aluminium has a low density compared to other metals which is why it is so lightweight. This low density is due to the total atomic mass of an atom because of the protons and neutrons of aluminium which add up to an average atomic mass of 28.98 which is lighter compared to most other metals.

Electrical Conductivity: High, 36 m/Ohm·mm²
Aluminium has very low electric resistivity and in turn very high electric conductivity. This property is due to the DE-localized electron (e-) in the "visualization" of a metallic element which allows the element to conduct electricity as the electrons are allowed to move freely and conduct an electric charge

Chemical Properties
Oxidation
One key chemical property that sets aluminium apart from other metals is when it is exposed to oxygen (O2) it reacts to form aluminium oxide (Al2O3) which make a thin sheet on the surface of aluminium which prevents it from rusting.

Reaction with acids and bases
Aluminium can react with both acids and bases which makes it unique from other metals as it is unusual for one element to be able to react with both.
