AluminiumIntroduction: The element aluminum has the symbol Al and an atomic number of 13. It is a very light, soft and useful metal used for many things such as cans, aluminum foil and cooking utensils. It is a ductile metal, a good conductor of heat and electricity, does not corrode and is solid at room temperature. It was discovered in 1825 by Hans Christian Oersted in Denmark. Aluminum is one of the most used metals in the world as well as one of the most commonly found metals in the Earth's crust.bit.ly/1jKzUg3Physical and Chemical Properties: Each element on the periodic table has physical and chemical properties different. The physical characteristics of an element are those characteristics that can be seen without transforming the element into another substance. Some physical properties include: color, hardness, freezing point, melting and boiling point, density and luster. Aluminum is a very shiny, silver-white metal with a blue tint. It is a light but strong metal. It is a very soft metal which makes it very easy to shape. Aluminum has a hardness of 2.75. This means it's hard enough to scratch your fingernail but soft enough to be scratched by a penny. Each element has a unique density, density measures the strength of an object. Aluminum has a density of 2.7 grams per milliliter. This means that aluminum can still sink in water even though it is light. The melting point of aluminum is 660.323°C and ...... middle of paper ...... oxygen in aluminum produces CO². The end result is liquid aluminum which is then sent into extrusion slabs. The aluminum is now ready to be processed into other products.http://bit.ly/1cZ1e2pWhat is the structure of the aluminum atom?The core inside the aluminum atom is made up of 13 protons and 14 neutrons and 13 electrons in electron clouds. In the first electron cloud, there are 2 electrons, in the second, 8 electrons and in the third, 3 electrons as shown in the diagram below.http://fla.st/1cpwScHConclusionIn conclusion, we see that the Aluminum is a very important element. It is a useful metal that can be used in many areas of life, from transportation to electricity and much more. The fact that it is easily recycled also makes it very efficient. It can be used daily in many areas of everyone's life..
