Describe how bonds the form: Aluminum is found in the Earths crust, not pure, but along with other elements. The formulas for a couple of the compounds that contain aluminum from the crust are: Al (OH) 3 and AlO (OH). They have an ionic bond naturally within the earths crust. Aluminum is makes up most of the Earths crust. Aluminum has very unique mix of properties. Al is very usable and is used in a lot of construction work. Al has a very lightweight and it has the 1/3 density of steel. Also to mention it is a very strong/tough element. Al has many other properties such as: elasticity, formability, machining, joining, corrosion resistance, conductivity, linear expansion, non-toxic and reflectivity. There is no impact on the environment from aluminum really. It is recycled just about everywhere and that’s pretty much all there is. There is a lot of impact that aluminum has on our society today. A lot of the things we use are made of aluminum. Such as you bike, pipes, wheels rims, ramps, flagpoles and the two big ones would be aluminum foil and the body of our Mac Books. Advantage of using aluminum in our product would be its weight and strength. Just like the advantage Apple takes on using aluminum, instead of heavy metals, its aluminum. No disadvantages.

what factor was the driving force/s for the change using the first common material. The first tennis rackets had a wood frame and intestine strings, therefore it wouldnt be very strong and probably didnt have a good performance in a game. One of the reasons for change would be: 1. found aluminium and it proved better in strength than wood. 2. they also found out about Kevlar/polyester which was better in performance that intestines. 3. the wood would've been heavy therefore= less power behind the swing so light but strong aluminum would put more power behind the swing. 4. the circular shape of the old tennis racket would've broken when the person swings it and it hits the ground on the tip of the racket but with the new rackets they are oval therefore a stronger tip. garnet
