Essay on The History of Chemistry - 1804 Words

The earliest knowledge of chemistry was in 3500 B.C in Egypt and Mesopotamia. Chemistry was concerned anything that was pottery, dyes or crafts that were developed but not considerable skills because no one truly understood its purpose. The basic idea of elements or compounds were first formulated by Greek philosopher during 500 to 300 B.C when people believed fire , water, earth, and air combined to form all living and non-living things. In the beginning of Christianity an ancient Egyptian and Greek philosopher were fused into the new ideas of science, starting with little experiments such as turning metal into gold or imitation of precious gems. Later on people such as Robert Boyle, Robert Hooke and John Mayow were just the few people†¦show more content†¦It was just he have not had any important discoveries of his own. They called him a theoretician. He saw the true nature of combustion something that the others didn’t see and introduce a chemical nomenclature and wrote the first chemistry textbook. Lavoisier believed that all acids contain oxygen. The assumption that compounds were definite was in the 18th century by J.L Proust, He stated that the law of constant proportions in 1797. C.L Berthollet said this law depends on the method of preparation. Soon enough it was resolved when Proust saw John Dalton’s atomic theory in 1808. The atomic theory goes back to Greeks but it was not a proven fact in chemistry until Humphrey Davy and J.J Berzelius discovered the alkali metals by passing an electric current through their molten oxides. Michael Faraday discovered that a definite quality of change must flow in order to give weight in the solution. Avogrodro introduced the hypothesis that equal volumes of gases at the same pressure contain the same number of molecules. Prout thought that all elements have an atomic weight and multiples with the weight of hydrogen. This hypothesis contributes to the periodic table. The periodic table was inde pendently found by J. L Meyer in Germany and D.I Mendeleev in Russia (1869). Adding on to that William Ramsay and Lord Rayliegh found other gases to extend the periodic table.Show MoreRelatedThe History of Chemistry Essay978 Words   |  4 PagesHistory 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. AlchemistsRead MoreThe History of Chemistry Essay798 Words   |  4 Pages Chemistry and technology are together and separate. Chemistry uses technology and technology uses chemistry. The history of chemistry and technology is long going back to the ancient times. Chemistry was used even by the oldest civilizations, like Egypt. It was really popular during the medieval times. Back then it was called Alchemy, which is turning metal into gold or even about the philosopher’s stone. As the years went by, Alchemy becam e a lost art and chemistry took it in place. Chemistry ledRead MoreEssay on The History of Chemistry844 Words   |  4 PagesChemistry is defined as, â€Å"the study of the composition, structure, and properties of matter, the processes that matter undergoes, and the energy changes that accompany these processes† (Davis 3). Chemistry has been around since the dawn of time, way before humans realized what chemistry was or its importance. The building blocks of the earth, such as minerals of the soil and atmospheric gases, all arise from chemical elements. Natural resources are all chemicals or chemical compounds, and the studyRead MoreThe History of Chemistry Essay844 Words   |  4 PagesChemistry 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, cosmet ics 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 sayRead MoreThe History of Chemistry Essay1235 Words   |  5 PagesThe History of Chemistry Chemistry is the science of the composition and structure of materials and of the changes that materials undergo. It is also used in improving standards of living, making it possible for such substances as rubber, nylon, and plastics to be made from completely different materials. New materials and new properties of old materials are always being discovered. Some earlier products discovered from chemical reactions are ceramics, glass, and metals. Dyes and medicinesRead MoreEssay on The History of Chemistry928 Words   |  4 PagesChemistry has been around for a very long time. Chemistry dates back to as far as the prehistoric times. If you put the amount of time chemistry takes up in a timeline, you would split it into four general categories. The four categories are: prehistoric times - beginning of the Christian era (black magic), beginning of the Christian era - end of 17th century (alchemy), end of 17th century - mid 19th century (traditional chemistry), and mid 19th centu ry - present (modern chemistry). It startsRead MoreEssay on The History of Chemistry: Chemistry is True Science619 Words   |  3 Pages Chemistry plays a key role in every branch of science. It has even been dated to times as early as the Prehistoric Era, and all the way up to now, the Present. We use Chemistry on a day to day basis. From Jewelry, to Fire-Works, Soap, and also, even the food we eat. Often people look at Chemistry and are bored because of the information they may not know. Science is everywhere, we just have to open our eyes and explore the world of Science. There is more to Chemistry than meets the human eye, andRead MoreHistory of the Science of Chemistry Essay882 Words   |  4 PagesThe history of chemistry makes a span of time reaching from ancient history to the present.

So what if chemistry sounds boring to some people, everyone has their own opinion about a subject that you don’t want to talk about in class or the subject you know so well that if someone asked you a question you could answer in a heartbeat. Well for me chemistry is the subject I don’t know very well at all and is hard for me to learnRead MoreEssay on The History of Chemistry and Its Influence on Society732 Words   |  3 Pages The history of chemistry has a span of time reaching from ancient history to the present. By 1000 BC. Ancient civilizations used a lot of different technologies that helped eventually form the different branches of chemistry. In my discussion about the history of chemistry, I will answer four questions that are very questionable. Such as, What was society like before the discovery of chemistry? How did natural resources limit or advance chemistry? How is chemistry affecting society today? And finally
