Origins of the Name
The word, Aluminium originates from the ancient Latin word for alum, alumen, which is potassium aluminum sulfate, meaning “bitter salt”. We pronounce the element of aluminium’s name as follows, al-yuh-min-ee-uhm, which conforms to the IUPAC pronunciation of the word, with the regular ‘ium’ ending of majority of the elements of the periodic table.
The History
Aluminium was first discovered in 1825, by early discoverer, Hans Christian Oersted in Denmark. Before this time, alum (the Ancient Latin word for Aluminium) was readily used throughout society for a multitude of reasons, such as a mordant in dyeing, a tanner for sun exposure, and as an astringent for medical purposes. Historically, it all began in the year of 1761, when scientist, de Morveau, proposed the name alumine for the base element found in alum. In 1807, Davey put forth his proposal on the name of aluminum for the element that was yet to be discovered. Soon thereafter, the IUPAC developed the word aluminium for the newfound element of the periodic table.

Isotopes
In total, Aluminium has approximately 23 known isotopes ranging from Al-21 to Al-43, with two of these isotopes occurring naturally on Earth. Aluminium isotope Al-26 with a half-life of 730, 000 years, is only found naturally on Earth in very small traces, and is formed by the cosmic-ray bombardment of argon in the Earth’s atmosphere. Alternatively, Al-27,

    But element 85 gives our study a greater depth than has yet been revealed by the already covered elements. What this story shows is that the nationalistic prejudices persist to this day in many respects and that the identity of the “discoverer” of the element very much depends on the nationality of the textbook that one might consult. It is also an element for which the majority of sources give an incorrect account in declaring Corson, MacKenzie, and Segrè as the true discoverers. The account I will detail owes much to the recent work of two young chemists, Brett Thornton and Shawn Burdette, whose 2010 article I have drawn heavily from.…

    One of the many elements on the periodic table is Aluminum. Aluminum is the 13th element, and it is located in period two and group thirteen. Aluminums symbol is Al and it has an electron configuration of [Ne] 3s2 3p1. Aluminum also has an atomic mass of 26.982 and its atomic number is 13. This element was discovered by Hans Christian Oersted in the year of 1825, and was named by the English chemist Sir Humphry Davy (Helmenstine, 2012). Its name ‘Aluminum’ came from the Latin words ‘alumen’ or ‘alum’, which is an astringent and dyeing mordant. Originally, Davy called it “Alumium’ but the publishers later changed it to Aluminum, and that’s how it remains in the United States (N/A, n.d.).…

    Aluminium and their alloys are widely used as construction materials from house hold appliances to air-craft parts. The commercially pure aluminium has merely low corrosion resistance and hardness compare to aluminium alloy. In this study an attempt has been made to study the influence of heat treatment on the properties of commercially pure aluminium. The investigation was consisted of identification of commercial aluminium through colour identification in chemical test and its subsequent heat treatment. The experimental parameters were heating temperature, cooling rate and quenching medium. The prepared specimen were heated at 300, 500 and 600 °C and then subsequently cooled either in open air, slowly in the furnace or quenched in furnace oil. Hardness of the heat treated and without heat treated specimen was measured in the Rockwell Scale. Corrosion resistance of the sample was evaluated in 3.5 % sodium chloride solution by weight loss method. It was found that specimen heat-treated at 500 °C showed higher hardness and corrosion resistance compare to that heat-treated at 300°C and 600 °C. Oil quenching specimen provided maximum hardness and corrosion resistance compare to slow furnace cooling and air cooling. So, it is said that hardness and corrosion resistance of commercially pure aluminium (99 % pure) could be improved through heat treatment at 500 °C and subsequent quenching in oil.…
