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
Dmitri Mendeleev, a Russian scientist, is said to be the father of the periodic table. In 1947 Mendeleev, while working on a textbook, began to organise the 63 elements that were known at the time in groups that displayed similar properties. Mendeleev found it difficult to classify certain alkali metals and metals, and while trying to find a way to classify them he began to notice that the properties and atomic weights of halogens and alkali metals shared similar patterns. He then began to investigate extensions of these patterns within the other elements. Mendeleev created a card for each of the known elements that sh...
In life and society as most of you know, chemistry is involved in everything in this entire world including; animals, plants, and even food! Although most people don’t like chemistry due to all the equations and “Stoichiometry”, it plays a significant role in everyday life. Thanks to many scientists in the past, we can now use the knowledge of their theories and postulates to find new technology and other scientific advancements to help the evolvement of many organisms in this world.

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.
“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.”
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.
What is chemistry? According to the American Chemical Society, chemistry can be described as “the study of matter and the changes it can undergo.” This science has been improved by many amazing scientists, and, because of them, our world have never been more advanced. Rosalind Franklin was one of those scientists, and she most definitely contributed to the science of chemistry.
Have you ever had a question about the History of Chemistry, because I just had one recently about the invention of Pepto-Bismol. This invention of Pepto-Bismol was a key invention to the society because this helped people cure their rare disease in the late nineteenth century that people called diarrhea. Today, I am going to take you on an adventure through time that was the late eighteenth century to the early nineteenth century and you will come to see that Pepto-Bismol was an amazing invention. Let’s start with the beginning stages of the creation of Pepto-Bismol.
Chemistry is a branch of natural science that deals principally with the properties of substances, the changes they undergo, and the natural laws that describe these changes. (University of Idaho, 2014) Molecules, as small as they seem, is in the food that we eat and present in our daily lives. Today, scientists would likely know about the history of chemistry but not how chemistry has impacted history. Many would not wonder if these molecules go beyond the chemistry concepts that they have learned. For example, would the world have been different if piperine (molecule) present in pepper had not led to the discovery of the United States? The interesting fact is that molecules have and will continue to shape the world today. In this book, the authors explain in detail how 17 specific molecules had a significant impact on the history of the world. On a whole, this book is very intriguing and very suitable for chemistry lovers as well as the general public.
Regarding, the copper and sodium chloride, no visible change occurred after 5 minutes had passed. The copper metal remained at the bottom of the test tube undeterred by the NaCl. There may not have been a reaction because copper is lower on the reactivity series than sodium.
Boyle has been fitly named, “the Father of Modern Chemistry.” Among his many accomplishments are the creation of the first gas law, Boyle’s Law, discoveries about what can and can’t pass through a vacuum, and an accurate definition of elements and compounds.
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...
“As the last drops fell from the glass to my tongue, I wondered - only for an instant - what perhaps I'd never know. What would it taste like, what would it feel like, if that liquid sliding down my throat was not champagne. But the elixir of life” (Neville). The concept of an elixir of life discussed in Katherine Neville’s book, The Eight, is by no means a new concept. In fact, it is one of the main goals of of a group of people, alchemists, who first recorded their workings 2500 years ago (Bateman). Alchemists have greatly shaped much of science and society.
Because other metals were thought to be less perfect than gold, it was reasonable to believe that nature created gold out of other metals found deep within the earth and that a skilled artisan could duplicate this process. It was said that once someone was able to change, or transmute a "base" chemical into the perfect metal, gold, they would have achieved eternal life and salvation. In this way, alchemy turned into not only a scientific quest, but a spiritual quest as well. Although the purposes and techniques were often times ritualistic and fanciful, alchemy was in many ways the predecessor of modern science, especially the science of chemistry.The birthplace of alchemy was ancient Egypt, where, in Alexandria, it began to flourish during the Hellenistic period. Also at that time, a school of alchemy was developing in China.
