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. Basic Facts

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,...
