What is chemistry? According to dictionary.com, the definition of chemistry- is the science that deals with the composition and properties of substances and various elementary forms of matter. Chemistry is everywhere. For example: in a kitchen, it is in everybody's chemically treated water, or fruits grown with fertilizers and pesticides, or polymer material in the marble counter tops. Again, Chemistry is everywhere. If a person wanted to go deeper into chemistry, they probably would state with the Periodic Table. The Periodic Table consists of many elements, for instance: Sodium (Na) is a metal, which is located in group 1, period 3, with an atomic number 11 and has a mass of 22.99. Chlorine (Cl) a nonmetal located in group 7A, also in period 3, with atomic number 17, and a mass of 35.45. When these two elements are put together, they make Sodium Chloride (NaCl), which is table salt that people use every day. In the periodic table, there are many different classifications of the elements like, Alkali metals, Alkaline Earth metals, Halogens, and Noble Gases. Out of all of the classification of …show more content…
Chemists are able to make many things once they understand the periodic table. For example, if a person wants to clean in his/her bathroom, they would probably use bleach, which is a sodium hypochlorite liquid and calcium hypochlorite as a solid. When a person uses soap to take a bath, they are using an element from the periodic table as well. The elements on the periodic table are widely used all over the world. Out of all the elements on the periodic table, noble gases are the most remarkable, because of their history on how and when they were found, their location on the periodic table, and how they are used in this world today. As time goes on, the elements will continue to be discovered by intelligent people, and the periodic table will continue to
