Chemistry is the explanation of science. Chemistry is also the explanation of mostly everything and the reason why we live so comfortably in the 21st century. If the Neanderthals of our past had even half the knowledge of chemistry as we do, we would be in flying cars and teleporting to our moon colony right now. That being said, we can definitely see how great the knowledge based in our everyday, seemingly mundane objects really are. We hold computers, calculators, touch screens, social mediums, task managers, calendars, and much more in our pockets every single day. That is mind blowing and it’s all thanks to the power of chemistry. Dipole-dipole Thermoset ([heat based curving) Polymer atoms are bonded to form a plastic film to laminate a circuit board. Then precious metals amounting to about”0.35 grams of silver, 0.015 grams of palladium and 0.0003 grams of platinum” are then duct into thin wires and placed to connect etchings on the board together, among other things. But let’s go back further. Let’s say around 3000 B.C. where ancient Egypt began the harvesting of meteoric iron (native iron) to create highly sought after “Daggers from Heaven” (Heaven referring to where the meteorites fell) to place with their dead or use for hunting, soon after they began metallurgy of gold and this lead into the Bronze Age. Everything was being smelted and metal worked in this era, the whole name of it is based on how much metal we were using. In 3500 people began smelting together tin and copper to create a new more resilient metal, Bronze. Though this is barely chemistry these early roots of understanding purification, melting, and bonding of metals pave the way of understand we have today. Next we move into the Iron Age where the blast fur...

...vin Created the theory of absolute zero, where all molecular motion stops, which is measured in Kelvins. Stanislao Cannizzaro began to practice Avogadro’s theory in front of groups of people and stated alkali metals and the alkaline earth metals are two different formulas so anomalies that occur when treating them as one would cease. William Crooke was credited with the cathode ray which helped us to understand and actually see chemistry. Then Mendeleev’s periodic table organized by valence number whilst missing the noble gases (which were undiscovered) in 1864 making every contribution to chemistry able to be seen so immediately that chemistry hasn’t changed much about it now. It’s strange that once you organize all of the elements by weight they become so easy to synthesize and are all related by mathematical entrancements. Well that’s all I have to say about that.
Miodownik describes in detail how natural elements were manipulated by man to create man-made materials at the same minuscule scale that take place naturally. Materials science has provided the knowledge required for
The Periodic Table is guidance or map to access different elements specific information, such as: atomic mass, isotopic richness, nuclear spins, electronic configuration and the position of elements belong to which group and period in table. Over the past decades there were many Scientifics which help to improvement of Periodic table but few of them made the most influence and contribution on Periodic table such as : Johann Dobereiner ,John Newlands , Dmitri Mendeleev and Henry Moseley.
In reference to both the chemist novelists, they have accurately identified several compounds that have found their way in history, but failed to mention the relationship between themselves and the changes each compound created. For example, LeCouteur and Burreson do state, “The Bronze Age, when bronze was used for weapons and tools was followed by the Iron Age, characterized by smelting of iron and the use of iron implements.”4 These chemists do note of their existence, (of bronze and iron), but failed to go into an in-depth analysis as to how each of them incorporative their usage to today’s time. Bronze for example, had shown a transition from burins tools for hunting to a durable ax and adz heads for agriculture. This ultimate transition had set the stage for a new era, filled with new findings and affects for further implications, like other metallic elements. Elements, like tin, in which LeCouteur and Burreson, state was material that the buttons from Napoleon’s army coats where made out of. This material wasn’t able to support the freezing conditions of Russia, which is believe to led have fallen apart. Nevertheless, the predicament came to be if, “the lack of buttons meant that hands were used to hold garments together rather than carry weapons?”5 Within missing chemical structures like bronze
It revolutionized our scientific ways of thinking, and it has enabled scientists to create new elements.
Dmitri Ivanovich Mendeleev, a Russian Chemist, was the start of all education and teaching for us. Throughout his life, he made great achievements when he was going through a deep illness. From his education of studying to inventing all sorts of things, he became known as the “ Father of the Periodic Table."
Attempts to organize the elements began in the late 1800’s. At this time, about sixty elements were known. Much advancement would have been impossible if the basic model of the atom was discovered. Great progress came from Dmitri Medeleev – a Russian chemist. His first draft of a periodic table was only the product of him attempting to summarize his knowledge of the elements. Although not all of Medeleev’s ideas were one-hundred percent accurate, they created a solid base to build upon. Marie and Pierre Curie; a married couple from Paris were successors of Medeleev. Their interests were radioactivity and discovered radium. The true pioneers of the periodic table were Ernest Rutherford and James Chadwick. Rutherford formed the hypothesis that, “An atom must have a concentrated positive center charge that contains most of the atom’s mass.” Following Rutherford, Chadwick exposed a segment of the nucleus that was had no charge: the neutron. With the basic knowledge of the structure of an atom, the tedious work of putting the rest of the puzzle together continued.
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.
Natural Philosophy also called philosophy of nature comes from the Latin phrase “philosophia naturalis”. Natural Philosophy is the philosophical study of the cosmos and nature’s elements and how the materials around the world are formed. There are many branches of natural philosophy including: cosmology, etiology, astronomy, probability, the study of matter, the study of elements, and many other subjects. The pioneers of natural philosophy are mainly pre-Socratic philosophers; the most famous philosophers of them were Thales, Democritus, and Aristotle. Thales argued that natural phenomena always occurred because of natural reasons; he refused the supernatural or mythological explanations. Another philosopher that contributed to natural philosophy was Democritus. Democritus, collaboratively with Leucippus, created the theory of atomism. While Aristotle, arguably the most iconic of all philosophers during this time period, further promoted the idea that natural phenomena is caused by natural reasons, which meant that it can be studied so that laws can be formed. Aristotle also wrote about metaphysic, poetry, music, physics, logic, politics, rhetoric, ethics, linguistics, biology, zoology, and theater arts. Aristotle also tried to discover the laws of motion and gravity.
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.
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.
Dalton’s idea is that all things are made of small bits of matter, these bits of matter where too small to be seen even with a microscope. Scientists began to think these small bits of matter were responsible for chemical changes. They thought that when these bits of matter combined, a chemical change took place. Dalton assumed that there was a special pattern in the elements and was partly responsible for the periodic table. Dalton in 1787 started to keep a journal.
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.
Then both Meyer and Mendeleyev built periodic tables alone, Meyer more impressed by the periodicity of physical properties, while Mendeleyev was more interested in the chemical properties. Then Mendeleyev had published his periodic table and his law in 1869 and forecasted the properties of the missing elements, and chemists then began to be grateful for it when the discovery of elements was predicted by the table that had taken place. Although, periodic tables have always been related to the way scientists thought about the shape and structure of the atom, and has changed over the years exactly for that reason.
Engineer dates back to 1325 when an engine’er, someone who operates an engine, was referred to by a conductor as an engineer. (Ford)
