Specific Element (Aluminum)
Aluminum is a unique metal that can be distinguished from other metals with its characteristics. It is very malleable and that is the reason it is used as a foil. It is silvery white in colour and very shiny. It's density is 2.7g/ml, Aluminum is a lightweight metal, but it still sinks in water. despite, its weight it is actually a strong metal. It's melting point is 660 degrees C and it's boiling point is 2500 degrees C. Aluminum is a very popular metal to use as it is very cheap and conducts electricity well in electronic devices. It is also used a lot to make the chassis of phones and laptops as it looks very nice and is easy to hammer.
Chemical Properties
Aluminum is a very special as it doesn't rust. On the outside it layer it forms a thin layer of oxide when there is moist air which stops it from reacting to the oxygen. This helps it stop rusting from attacking air. Aluminum is a reactive metal as it reacts to many kind of halogens and acids. It can also react to high heat. If Aluminum powder is exposed to heat, it can burn from oxygen and a white powder will be formed. This reaction also causes a lot of heat to be produced.
Compounds and Reactions
Aluminum is a reactive metal, it reacts with many different halogens. It reacts with iodine, chlorine, and bromine. It then forms aluminium(III) iodide, AlI3,aluminium(III) chloride, and aluminium(III) bromide, AlBr3. As mentioned above, it can react with oxygen and heat which will cause a white powder. This is called Aluminum Oxide 2Al2O3(s)
