Chemistry has been around for a very long time. Chemistry is the branch of physical science that studies composition, properties, energy, and behavior of matter. It is said that chemistry has been around since prehistoric times. This was in the form of everyday objects like pottery, cosmetics and perfumes, and extracting metals from ores. Chemistry is based on the discovery and study of elements. Some elements were known to ancient man, but most were discovered by chemists and alchemists. Some say that chemistry started in the early Stone Age when man made fire. Chemistry is the study of chemical composition and properties of matter and the reactions of that matter. The study of any living thing involves chemistry.
The history of chemistry dates back to the time of ancient history to now. Ancient civilizations used technologies that would eventually form the basis of the various branches of chemistry by 1000 BC. For example, they were extracting chemicals from plants to make medicines. The history of chemistry is intertwined with the history of thermodynamics. Chemistry is very important to our world today. Without it, we wouldn’t be near as advanced as we are. Let’s take scientists for example. The scientists at St. Jude children’s research hospital; everyday they are working to find the cure to various types of cancer by mixing different chemicals and making various compounds to somehow help all the children with the big C word today. Chemistry plays a big role in things we would never think of.
Everyone in my grade despised that class, it was hard, it was tedious… but I loved it! It opened my eyes, and allowed me to see the world from a different perspective. Everywhere you look, there it was, chemistry. The periodic table was the one that winked my eye at first. It is only a table to gather and organize information, yes! But for me, it is the work of multiple great minds, their legacy for the humanity. The periodic table is a graphic metaphor for perfection. Everything is in it’s right place, and it all has a function. All about the periodic table gives me hope in a way that nobody else can understand. It is a weird way to relate life and chemistry, but thanks to that peculiarity; it helped me make the grown up decision of my life,
...e process that makes up another. In addition, it is one of the links to the past and helps improve lives today. It has helped create new technology that has improved healthcare, food, and transportation. Without chemistry, we wouldn't have a lot of the products we have today, including colors and dyes. With all the atoms, electrons, chemical properties, and energy around, chemistry has made sense of it. Chemistry has certainly made an impact on the world.
Chemists are the specialists in chemistry, that interact with chemical properties, and reactions. The earth is made up of different gases. Some of this gases are needed for life in the planet but other gases can be harmful to the living. Gas’s use in regular quantities are favorable to the earth. The world started to become more advance and had to use more of this gases to produce everyday objects and inventions by men. Little did we knew this chemicals we going to affect us in our life. Chemist Jose Mario Molina actually discovered that chlorofluorocarbons were affecting the ozone layer.
Part A HISTORY of the PERIODIC TABLE
Antoine-Laurent Lavoisier discovered both hydrogen and oxygen, although it is said that Henry Cavendish had earlier uncovered hydrogen. Lavoisier also helped create the metric systems (source 1). He wrote the first extensive list of elements containing 33 elements and distinguished metals and non-metals (source 5). Him and his area of work were particularly interested in compounds, element weight and chemical reaction (source 6).
Dimitri Mendeleev arranged 63 known elements, into the periodic table based on atomic mass and predicted the existence and properties of new elements.
Science branches out to the research of anything ranging from life to the latest technology. It has a vital influence in the development of new things that might improve our everyday life. Some researchers help us learn what not to do with certain elements. A chemist to be specific, does exactly that. According to Emporia State University, a chemist is a scientist who focuses his/her studies toward that involves of chemicals. Becoming a chemist isn’t easy, but it is a career that contributes to society.
Throughout my school career I have always loved chemistry. In Chemistry there was always a sense that there was more, there was always something new and exciting to be discovered and theories to be proven (or even disproven). Chemistry was the main subject with a real practical aspect to it during school and it is this, along with my genuine fascination with the subject, which fuels my desire to study it further.
Chemistry is the most fascinating science to me. Chemistry applies to all things in the universe; living or non-living. Everything is made of elements which are made up of atoms of a certain atomic number. Thereafter I took AP Chemistry, I knew I had to choose a career in the field of chemistry. I understand and enjoy learning about chemistry. Chemistry is important, interesting, and ever expanding. Therefore, I must pursue a career in Chemistry.
...ree careers make sure that every day activities do not lead to the degradation of the environment. For these reasons, it is clear that chemistry is beneficial to the way of mankind.
