Describe the importance of alloys, plastics and polymers in Society.
Plastic: __**** It is a substance that has a change in temperatures that give the plastic flexibility and elasticity that let them be molded and adapted into different shapes. It is a polymer made of Petroleum, Carbon and other natural substances. Plastic are almost used for everything, but mostly for trash bags, parts of cars, computers, furniture, for construction, etc. However plastic is a high contaminating source because it biodegrades in 500 years which is too much. That is why now plastic is being recycled and more biodegradable plastics are being produced. **
 * __ Alloys: __**** It is a metal or solid solution composed of more than one element. One alloy is brass, which is composed of Zinc and Cooper. This alloy is important for society because it is used to make musical instruments, jewelry, plumbing, etc. So thinking of these two alloys we can say that a **** lloys are essential to construction and transportation. They can join the properties and characteristics of two or more metals to create a hybrid metal that is more effective, stronger, and durable. **
 * __ Polymers: __**** Are substances containing a large number of structural units joined. These substances often form into a chain-like structure. Polymers in the natural world have been all around since the very beginning. Starch, cellulose, and rubber have polymeric properties. Today, the polymer industry has grown and it is larger than the aluminum, copper and steel (alloys) industries combined. **

** · Sports: Playground equipment, balls, swimming pools, and protective helmets are produced from polymers, mostly. **

=Subatomic particles=

Years ago the atom was discovered, it was thought that the atom was the smallest thing that can be split in matter. That is why it is called ATOM that means "no cut". But some years later it was discovered and proved that there were smaller things than atom, that are the subatomic particles. This subatomic particles are the electron, this subatomic particle has a negative charge and are not found on the nucleus but in the orbits; the neutron doesn't have an electric charge and can be found on the nucleus; the proton has a positive charge and it is found on the nucleus. It was thought that this subatomic particles can not be divided into smaller things. Now it is know that the electron, the neutron and the proton can be split. They can be split into quarks. There are 6 types of quarks that are: UP, DOWN, CHARM, TOP, BOTTOM, STRANGE. Three of this types of quarks were so inestable that dissapear and only 2 types of quarks (UP, DOWN) were left.The proton and the neutron have three quarks each. The proton has two UP quarks and one DOWN quark. And the neutron has one UP quark and two DOWN quarks. I am not shure if electron can be split [|Our best evidence also shows us that there is nothing inside of an electron except the electron itself]. May be in some years it will be proved that the quarks can be divided into smaller things, and those things into smaller ones, etc.
