Introduction to Aluminum

What is Aluminum?

Aluminum exists as a metal which displays both lightweight properties and a silvery-white appearance, yet it contains exceptional characteristics that make it one of the most frequently used elements throughout the periodic table. Aluminum exists as a post-transition metal which belongs to the boron group and has the chemical symbol Al and the atomic number 13. The element occurs as the third most common element in the Earth’s crust, where it exists at a weight percentage of 8% and primarily appears as bauxite ore.

Aluminum has high reactivity owing to its nature, yet its surface gets covered in oxide layer which inhibits any corrosion. This material combines high corrosion resistance with high electrical conductivity and plasticity, to weight strength which makes it necessary for various industrial applications. The material still proves to be indispensable in modern engineering in detail and also present environmental issues considering that the aluminum is reuse as such practices do not proceed to the nature’s depletion.

Historical Context of Aluminum

It is within the eighteenth and nineteenth centuries when an aluminum compound was discovered and in which bauxite was categorised as one of its minerals. In 1825, for example, aluminum was retrieved as a metal by the Danish physicist named Hans Christian Ørsted, although the amounts of the metal created were quite small. The Hall Héroult process was born out of necessity in 1886 for obtaining aluminum by electrolysis without the use of aluminum oxide developed by Charles Martin Hall and Paul Héroult. At this stage, the emergence of aluminum as a material for the manufacture and consumption of goods occurred.

Due to modern methods of extraction and processing, aluminum continues to rank among the most extensively produced non-ferrous metals. Statistics for 2023 suggest that the annual output of aluminum is more than 65 million felts because the need growth in the international economy, meaning transportation, construction as well as aerospace and renewable energy sectors, is ever increasing. Important achievements have been realized in the industry in terms of recycling technology development because The Aluminum Association predicts that about 75 per cent of the entire volume of aluminum ever produced is utilized productively in modern times. This is good for the economy, it is also good for the planet.

Chemical Properties of Aluminum

Oxidation States of Aluminum

The oxidation number held by aluminum remains at +3 during its reactions from where we can infer that it is its most predominant oxidation number. The element aluminum, in particular, exhibits this character because the three outermost electrons for the element are very mobile in any chemical change it takes. These electrons are above the core and upon joining chemical bonds they are excited leading to Al³⁺ anions which are very stable due to the fully filled or octet principle of stability.

An increased number of users has been identified searching for the oxidation behaviour of aluminum with partly naive questions like, “Why is aluminum always +3?” or “Give examples of +3 charge of aluminum compounds”. There is general agreement already of the key part played by aluminum in industry processes. It is because when the compounds of aluminum such as aluminum oxide (Al₂O₃) and aluminum sulfate (Al₂(SO₄)₃) are popular in business’ s practice, it would be expected that aluminum should be in +3 oxidation state most of the time.
