The History of Chemistry is ancient, starting at 1000 B.C to present time. Chemistry has evolved drastically over the centuries. the first civilization to take over chemistry were the Egyptians and Babylonians founded practical knowledge concerning the arts of metallurgy, pottery and dyes, but didn't develop a systematic theory.
In this period of time tons of civilizations tried to figure out the life of chemistry and how it worked. A basic chemical hypothesis first emerged in Classical Greece with the theory of four elements by Aristotle in 300 BC where fire, air, earth and water were the fundamental elements from which everything is formed as a combination.
Greek atomism dates back to 440 BC, arising in works by philosophers such as Democritus and Epicurus. Unlike modern concepts of science, Greek atomism was basically just the philosophical in nature, with little concern for empirical observations and no concern for chemical experiments.
In 1700 BC with the scenario of King Hammurabi's reign over Babylon there where several metals recored found at the site. In 430 BC Democritus of ancient Greece and man named Democritus proclaimed the atom to be the simplest unit of matter being that all matter was composed of atoms. All of the discoveries that were made at this time we still us as the foundation to chemistry.
There are many bumps and flaws in the business of chemistry as in the trying times for the Gold industries,13th Century through the 15th Century. Although Pope John XXII issued an edict against gold-making, the gold business continued. Despite the alchemists' efforts, transmutation of cheap metals to gold never happened within this time period.

...as heroine, marijuana etc. in the hands of people who take an advantage of he life of chemistry and drastically put the future at risk another example is of preservatives. These preservatives help to keep our food from getting bad but also at the same time causes many diseases.
In your opinion, what impact will your technology have on the future?
Personally I think that is will have equally a good and bad future. I think this because there are lot of things that can go wrong with how advanced our future will be from technology in and from how our world is today. Yet again it can be good because how advanced our future will be the “bad” things wouldn’t be able to happen. I am excited to see how out future will be and anxious to see if it will be good or bad.
All and all we’ed be stuck in the past without chemistry and wouldn’t be even close to where we are now.
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...
Dalton’s atomic theory, which stated “the atoms were tiny, indivisible, indestructible particles” (Bender), differed drastically from that of the Greeks’ in that it “wasn’t just a philosophical statement that there are atoms because there must be atoms” (Bender). Although Aristotle believed that there are four terrestrial elements, earth, water, air, and fire, Democratus believed that “a piece of a substance can be divided into smaller pieces of that substance until we get down to a fundamental level at which you can’t divide the substance up and still have pieces of that substance” (“Atoms”). Aristotle’s theory was popular, but incorrect; Democratus’s was closer to our current theory, yet he remained relatively unpopular and obscure. This demonstrates of the key way in which a personal point of view can, in fact, retard the pursuit of knowledge. The scientist with the better oratory abilities has his theories more widely accepted. Dalton’s own theory, which extrapolated upon four basic
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.
In the beginning, Democritus discovered that matter is made of atoms in 380 B.C. (Doc. 1). He said that each substance is composed of one type of atomos (OI). The next person to expand on this topic was Aristotle. In his experiment, he found that there was no empty space in the atom. He said that there is only Earth, Water, Air, and Fire (OI). More people included and constructed what the atom is made up of. The last person to discover something new with the atom was Rutherford. He made an experiment that would test
Many scientists helped with this. In 465 B.C. Democritus named the atom “can’t be divided” (OI). He proposed that matter was made of atoms (Doc. 1). Later, Lavoisier introduced the Law of Conservation of Matter. It stated that matter couldn’t be created or destroyed. After that, John Dalton published the Atomic Theory of Matter in 1803 (Doc. 2). It said that matter is made of atoms that are too small to be seen by the naked eye, and that each type of matter is made of only one kind of atom (OI). J. J. Thomson observed electrons using cathode rays. A few years later, Ernest Rutherford bombarded an extremely thin piece of gold foil with positively charged alpha particles. Most of the protons passed through the foil, but some bounced off. Rutherford concluded that the atom must be composed of mostly empty space. He also realized that the alpha particles must have bounced off something else that had positive charge. The positively charged objects were protons. Neutrons were discovered by James Chadwick. To conclude, the theories of the atom have been modified a lot since the
The chemistry aspects provided in the book was very detailed but there were some information lacking in the historical aspects of the book. The authors’ were also quick to conclude on how certain molecules were the sole factor responsible for the historical events. Although there are flaws in the book, this book is still an interesting read. The book is strongly recommended to the general public as it is able to provide to them a basic general understanding of chemistry and allows them to gain new knowledge and great insights into chemistry.
When people think of comparison and likeness, they rapidly jump to immediate observations and obvious detections. They fail to perceive the more imperative and subtle attributes. Whether anybody knows it or not, everything that inhabits the world and even the universe is alike in at least one way. All of these substances contain matter. Matter is the physical substance which encompasses everything, from dusty nebulas to the food on one’s dinner plate. It can be described as anything that has mass and takes up space. Within this matter are infinitesimal particles called atoms. So far, they are what scientists believe to be the smallest part of anything and can even be synthesized in labs (Oxlade 7.) The knowledge scientists possess of atoms is huge, in contrast to their microscopic size. In fact, modern day scientists would not have even obtained this knowledge if preceding chemists and physicists did not unveil what was covered. They paved the way to the vast expansion of awareness and allowed the atom to be seen in its true form. However, these impeccable discoveries did not spawn from a single human being, but rather from a chronological timeline of coincidental events.
The concept of an “atom” first began in ancient Greece. According to Delgado, early philosophers “suggested that regular solids were fundamental parts of the universe, and Democritus’ teacher, Leucippus, had introduced him to the idea of an atomic system.” However, it wasn’t until the

The idea of the atom started all the way back from the ancient Greece. What is sad about this is that one philosopher’s idea it was rejected by the rest of the philosophers of the time. Philosophers like Aristotle. The ancient Greeks did not have all the modern technology we have now and were not equipped to test their atomic theory. The theory they had hypothesized was if you keep dividing something, the smallest living thing had to be an atom.
Although the periodic table wasn’t formed until 1869 many studies were made previously into the structure of the atom. In 350 BC, Aristotle, a Greek philosopher, had a theory that all matter was made up of the elements; earth, fire, air and water.7 It was a belief of his that the lighter objects had less earth than the heaver ones. Democritus made studies soon after Aristotle’s statements about the behavior of atoms. Democritus believed that “The universe is composed of two elements: the atoms and the void in which they exist and move.” 6. Democritus proposed five key ideas about the way atoms move and exist.
The Atomic Theory began in roughly 400BC with Democritus in Ancient Greece and is universally believed to be correct today. Democritus who was born in 460 BC and died 370 BC and is known as the father of modern science. Democritus proclaimed that everything is made up of atoms. He continued his theory to say that atoms will always be in motion, between atoms there is empty space, atoms are unbreakable, there are an infinite number of atoms all different sizes and shapes. He also said that iron atoms are solid and strong and have hooks to lock them together, water atoms are smooth and slippery, salt atoms have sharp jagged edges because of its taste and air atoms are light and spiralling.
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.
