History of Chemistry
Chemistry has been around for a various amount of years. The beginning of chemistry was first acknowledged in 10,000 BC. The ancient civilizations used technologies that came to become the makeup of the many branches of chemistry. These early civilizations would extract metal from ores, make pottery and glazes, beer and wine fermentation, extraction of chemicals from plants for medicine, making fat into soap, making glass, and many chemistry related tasks were done. Alchemists set the stage for modern chemistry by performing experiments and recording the results. Robert Boyle wrote The Sceptical Chymist in 1661, and in this book it he talks about the difference between chemistry and alchemy. Although was not the original discover of chemistry, he is best known for Boyle’s law in 1662. Antoine Lavoisier helped chemistry become a full-fledged science when he a law of conservation of mass. The law of conservation of mass relates to chemistry because it requires a careful measurements and quantitative observations. Later, Jan Baptist Van Helmont suggested that there are other substances other than air and gave them the name “gas.” Gas originated from the Greek word “chaos,” and was soon used commonly amongst scientist. Van Helmont conducted several experiments involving gases. He is mostly remembered today for his ideas on spontaneous generation, his five year tree experiment, and also being considered the founder of pneumatic chemistry. In 1702 Georg Stahl came up with the name phlogiston to refer to the substance released in the process of burning. In 1735 Georg Brandt analyzed a dark blue pigment found in copper ore. He demonstrated that the pigment that he had found contained a new element. Brandt had discove...

...e Molecule, which discussed that a chemical bond is a pair of electrons shared by two atoms. Lewis was the one to introduce the electron dot diagrams, Lewis structure. Lewis structures can be found in almost every introductory chemistry book. Chemistry has long past to it, and has an even larger future ahead of it. Before chemistry there were so many questions amongst people about how things worked and why things were certain ways. The natural resources that surrounded everybody was definitely a great foundation and start for early chemistry discovery. Chemistry is something that is used every day. We use chemistry for making medicines, food, and many other tasks. I do think that chemistry will have a large impact on our future because it already has had such a large impact on oour past, and now that we have stemmed off others findings we can make them more advanced
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.

Genetics relies on chemistry to explain phenomena related to the field. The structure of DNA relies on chemistry. In fact, when James Watson and Francis Crick discovered the structure of DNA, they did so by building models based on the laws of chemistry. Chemistry also relates heavily to the structure and function of one of the main products of DNA: protein.
“The historian Bruce T. Moran, for instance, asserts that alchemy was an intellectually valid discipline in its contemporary context, that alchemy and chemistry were strongly interrelated, and that the exchange of ideas between the two can be seen in the works of figures like Robert Boyle and Isaac Newton.”
periodic table is arguably one of the most important developments in the history of all science. Development of the table spanned over more than 2000 years beginning with the proposal by Aristotle around the year 330 BC that there is limited number of elements (though at the time he referred to them as roots) that make up everything in the universe, though he believed these elements to be simply "water, fire, earth, and air" and made no further contributions to the development and understanding of the table and its properties.
The first theory to do with the atom was by Democritus and Leucippus who first proposed the idea of the atom as an invisible particle that all matter is made of. However, the first real discovery of an element, besides those like Gold and Silver etc. (which people had been aware of before written history) was phosphorus, which was discovered by Henning Brand in 1649. In 1787, a French chemist called Antoine Lavoisier, made a list of all 33 known elements of the time. Between 1649 and 1869, the Periodic table was added to and in 1869 a total of 63 elements had been discovered. In 1864, John Newlands made a huge advancement in the arranging of these elements, as he was able to sort them in order of atomic weights and was also able to observe similar properties between elements. The creation of the Periodic table, however is considered to be done by Russian scientist Dimitri Mendeleev who proposed a table as a classification system for all of the elements that had been discovered and he even left spaces for elements that had not yet been discovered, but he predicted they would. The Periodic table contin...
Natural sciences have always interested mankind, and throughout civilization, we have sought to discover how the world works. This natural curiosity is best fueled by scientific thought and reason. Science is a constantly evolving area of study, and scholars in the previous centuries sometimes took a mystical view on science, one of these areas of study is alchemy. Many significant men contributed to the study of alchemy. Four of the most prominent include: Albertus Magnus, Cornelius Agrippa, Paracelsus, and Allesandro Volta. Although their ideas are considered erroneous by modern standards of science, they still had important scientific investigations and influenced scientific advancements in centuries to come.
Brief History Jöns Jacob Berzelius, a physician by trade, first coined the term "organic chemistry" in 1807 for the study of compounds derived from biological sources. Up through the early 19th century, naturalists and scientists observed critical differences between compounds that were derived from living things and those that were not. Chemists of the period noted that there seemed to be an essential yet inexplicable difference between the properties of the two different types of compounds. The vital force theory (sometimes called "vitalism") was therefore proposed (and widely accepted) as a way to explain these differences. Vitalism proposed that there was a something called a "vital force" which existed within organic material but did not exist in any inorganic materials. {text:bookmark-start} {text:bookmark-end} Friedrich Wöhler is widely regarded as a pioneer in organic chemistry as a result of his synthesizing of the biological compound urea (a component of urine in many animals) utilizing what is now called "the Wöhler synthesis." Wöhler mixed silver or lead cyanate with ammonium nitrate; this was supposed to yield ammonium cyanate as a result of an exchange reaction, according to Berzelius's dualism theory. Wöhler, however, discovered that the end product of this reaction is not ammonium cyanate (NH4OCN), an inorganic salt, but urea ((NH2)2CO), a biological compound. (Furthermore, heating ammonium cyanate turns it into urea.) Faced with this result, Berzelius had to concede that (NH2)2CO and NH4OCN were isomers. Until this discovery in the year 1828, it was widely believed by chemists that organic substances could only be formed under the influence of the "vital force" in the bodies of animals and plants. Wöhler's synthesis dramatically proved that view to be false. Organic chemistry focuses on carbon and following movement of the electrons in carbon chains and rings, and also how electrons are shared with other carbon atoms and heteroatoms. Organic chemistry is primarily concerned with the properties of covalent bonds and non-metallic elements, though ions and metals do play critical roles in some reactions. The applications of organic chemistry are myriad, and include all sorts of plastics, dyes, flavorings, scents, detergents, explosives, fuels and many, many other products. Read the ingredient list for almost any kind of food that you eat — or even your shampoo bottle — and you will see the handiwork of organic chemists listed there. {text:bookmark-start} {text:bookmark-end} Major Advances in the Field of Organic Chemistry Of course no description of a text should be without at least a mention of Antoine Laurent Lavoisier.

Though many people fail to realize it, chemistry is a subject essential to everyday life, due to the fact that it is the branch of science that deals with the identification of the substances of which matter is composed. But what we must understand is that everything in the universe is composed of matter, hence chemistry is necessary in learning more about the world and universe that we live in. There are many careers and fields affiliated with chemistry that people pursue to learn more about the composition of the universe, but for now, let us examine the logistics of three of these careers. These three careers involving chemistry are geochemistry, environmental chemistry, and chemical engineering.
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.
I feel personally that the discovery of the atom was an important discovery for the world. With the discovery we are now able to answer questions we never even thought to ask. We are also answering questions some people asked long ago. We can now use our vast knowledge of the atom to measure the stars and be able to tell you what the stars are made of. The atomic discovery also helped us find our periodic table of elements. The periodic table of elements is a huge scientific chart that shows important facts with the help of its formation. There was a lot of constant scientific research that went into making the periodic table of elements and what it is today.
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.
Science and Technology has been around from the beginning of time. It evolved from the everyday efforts of people trying to improve their way of life. Throughout history, humankind has developed and utilized tools, machines, and techniques without understanding how or why they worked or comprehending their physical or chemical composition. Before we go any further a definition has to be given for both Science and Technology because they are both different in their own right even though the two are almost indistinguishable. According to the Oxford Dictionary Technology can be defined as the knowledge or use of the mechanical arts and applied sciences, while Science can be defined as the branch of knowledge involving systematized observation and experiment. Science can be further divided into three separate categories; Pure, Applied and Natural Sciences. In addition technology is often defined as applied science, it is simply the application of scientific knowledge to achieve a specific human purpose, however, historical evidence suggests technology is a product of science.
