Silvery white metal, surface covered with thin layer of oxide that helps protects the metal from attack by air. Odourless, Smooth texture, if wrinkled, sharp at that spot. Tastes metallic if eaten
Behaviour with other matter:It reacts vigorously with halogens to form aluminum halidesIt dissolves with the acids to form solutions
Aluminums ions can react with phosphates which causes phosphates to be less available to water organisms, which is a negative effect
Uses:Electrical-->Aluminum is low density, so it’s good for long distance power lines, and it’s a great conductor of electricity. It’s also used for satellite dishes and it’s a standard base for bulbs.
Packaging-->Drinks, foil paper, cans, bottle tops, foil containersHousehold objects-Saucepans, utensils, golf clubs, tennis bats, furniture, fridges, and toasters Building-->aluminum has really good corrosion resistance, it’s also very versatile. It can easily be curved, tapered, welded, bonded or cut to any shape.
Abililty to form compounds:All of earth’s aluminum has combined with other elements to form compound. The 2 most common compounds are: Potassium aluminum Sulfate KAl(SO4)2•12(H2O and alulminum oxide Al2O3.
•Scientists were already aware of “alum” (oxidized aluminum) since 1787•In the early 1800’s, Humphrey Davy established the existence of aluminum, but didn’t produce any. •10 years later, a French scientist found hard red clay containing over 50% aluminum oxide.•It was named bauxite (aluminum’s ore)•In 1825 Hans Christian Oerstad produced a small amount. •Later, Fredrich Wöhler, isolated aluminum by mixing anhydrous aluminum chloride with potassium.
Fun Facts:-Ever min of the day, about 123,000 aluminum cans are recycled-Since 1972, about 660 billion beverage cans have been recylced-placed end to end, they could streach to the moon 300 times.
Aluminum is mostly found in the form of Bauxite (Aluminum’s ore). Bauxite is found all over the world in places such as: Australia, Brazil, Guinea, Jamaica, Russia, and the U.S.
Where it's found:One of the most abundant elements in the earth’s crust,makes up 9% of it. It occurs in nature as a compound, never as a pure metal because of it’s affinity to oxygen.
If you try and take away oxygen with a flame, aluminum burns combustion Without oxygen aluminum is very corrosive, with it, its much less
