It's worth noting that despite the naming controversy he caused, Davy neither discovered the element nor isolated it! In the 1990's, the International Union of Pure and Applied Chemistry formally determined element 13 should be aluminium, yet the -um spelling persists in the U.S. Chemists in the United States actually used the -ium ending, shifting toward the -um ending in the 1900s. The -um spelling persisted in Britain for a while, eventually changing to aluminium. Davy changed the name to aluminum and then finally to aluminium in 1812. Davy initially called the element alumium in 1807, from the mineral alumina. We can blame the English chemist, Sir Humphy Davy, for the confusion.
The name for element 13 has been either aluminum or aluminium. In fact, you can even recycle the element at home, if you like. Only 5% of the energy needed to purify aluminum from alumina is required to recycle aluminum from scrap. In 1884, the cap of the Washington Monument was made using aluminum because the metal was so highly valued at that time. Napoleon III served dinners to his most important guests on aluminum platters, leaving lesser guests to dine using gold! It was so difficult to obtain element 13 that is was considered a precious metal. The modern process requires considerable energy, yet it's much easier than past refining methods. Aluminum ore (bauxite) is mined, chemically refined into alumina (aluminum oxide) using the Bayer process, and finally refined into aluminum metal using the electrolytic Hall-Heroult process. Aluminum is the third most abundant element in the Earth's crust (about 8%) and the most abundant metal. Aluminum is strong, yet light compared with most other metals. Unlike many other metals, aluminum is not very ductile, which means it isn't readily drawn into wires. Most people are familiar with the pure element's appearance from aluminum foil or cans. Pure aluminum is a soft, nonmagnetic silvery-white metal. Foils, cans, window frames, cooking utensils, beer kegs, and airplane parts are just a few examples of how aluminum is utilized in everyday life. Aluminum chloride and colorless hydrogen gas are produced when the metal aluminum dissolves in hydrochloric acid. Aluminum is highly reactive, non-magnetic, soft and flexible and naturally superconductive, belonging to the Boron Family. Pure aluminum does not occur in nature due to its proclivity for reacting with other elements. Aluminum is a silvery-white metal that has more than 8% of the planet's total core mass of Earth,. Packages, telescope mirrors, ornamental paper, and toys all benefit from aluminum coatings. It does not corrode in the same way as a silver coating does. Aluminum creates a highly reflective covering for both light and heat when it is evaporated in vacuum. It is less expensive than copper and has a weight that is roughly two times that of a conductor. Aluminum is also a good electrical conductor, which is why it is extensively employed in electrical transmission lines. They are crucial in the manufacture of airplanes and a variety of other modes of transportation. Copper, magnesium, manganese, and silicon alloys, on the other hand, are light yet strong. As aluminum is not very robust, it is commonly employed in the form of an alloy. As it's simple to cast, shape, and machine, and it's resistant to corrosion. Here are some important uses of aluminum. According to the equation, aluminum interacts with water to generate hydrogen gas. 2NaOH + 2H 2 O → 2NaAlO 2 + 3HĪluminum metal forms a thin coating of aluminum oxide, a few millimeters thick, that prevents it from interacting with water. Once formed, the reaction is extremely exothermic and is accompanied by the fast development of hydrogen gas.ĢNaOH + 2H 2 O → 2NaAlO 2 + 3H. The action of sodium hydroxide on elemental aluminum, which is an amphoteric metal, also produces sodium aluminate. The chemical reaction between aluminum and hydrochloric acid is irreversible.ĢAl + 6HCl –> 2AlCl 3 + 3H 2 → 2AlCl 3 + 3H 2 Aluminum chloride and colorless hydrogen gas are produced when the metal aluminum dissolves in hydrochloric acid. Here are the chemical properties of Aluminium-Īt room temperature, aluminum reacts with dilute hydrochloric acid. It has a density and rigidity roughly one-third that of steel. In nature, aluminum is a highly reactive metal. The color of aluminum is silvery-white.
The following are the physical characteristics of aluminum.

Though aluminum was created for the first time in 1824, but it took another fifty years for humans to figure out how to mass-produce it Aluminum is a silvery-white, soft metal which is non-magnetic and belongs to the Boron Group in the periodic table.
