2 Physical Properties -Aluminum is a pure substance. -It’s a shiny, silvery white metal.-It’s light in weight but very strong.-Aluminum’s density is 2.7g/ml which means it will sink in water but it is still very light.

5 Uses of Aluminum -aluminum is used everyday by average people: -they are used in the making of cans and foils.-mostly used in as kitchen utinsels-outside building decoration-alloys are of vital importance in the construction of modern aircraft and rockets-aluminum, evaporated in a vacuum, forms a highly reflective coating for both visible light and radiant heat. These coatings soon form a thin layer of the protective oxide and do not deteriorate as do silver coatings. These coatings are used for telescope mirrors, decorative paper, packages, toys, and in many other uses
6 Where aluminum is found -Aluminum metal is not found as the free element, aluminum is an abundant element in the earth's crust [ppb = Parts Per Billion]Location ppb by weight ppb by atomsUniverseSunMeteorite (carbonaceous)Crustal rocksSea waterStreamHuman
7 Chemical properties: Aluminum -The surface of aluminum metal is covered with a thin layer of oxide that helps protect the metal from attack by air. So, normally, aluminum metal does not react with air. If the oxide layer is damaged, the aluminum metal is exposed to attack. Aluminum will burn in oxygen with a brilliant white flame to form the trioxide aluminum(III) oxide, Al2O3.-Aluminum metal is obtained from the pure hot molten Al2O3 by an electrolytic method. The electrolysis of the hot oxide in a carbon lined steel cell acting as the cathode with carbon anodes is the most common method.
8 Facts-Aluminum was discovered by Hans Christian Oersted in Isolated by Friedrich Wohler in Charles Martin Hall received a patent in 1886.-Ancient Greeks and Romans used alum as an astringent, for medicinal purposes, and as a mordant in dyeing.-It is estimated that since 1972 some 16 million tons of aluminum cans have been recycled. These billion aluminum cans placed end-to-end could stretch to the moon more than 249 times.-Transportation (automobiles, aircraft, trucks, railway cars, marine vessels, bicycles etc.)
