Chemistry has been around for a long time. Chemistry wasn’t a huge subject back in the days because nobody knew what it was. If you asked a caveman if he knew anything about Lewis Structures, he would most likely be confused. Before Chemistry was founded, people were still very interested with elements. In fact some of our time periods are named after elements such as the Bronze Age and the Iron Age. Early humans used the metals as tools and weapons for everyday purposes but that’s about it because our technology wasn’t fully prepared. Prior to the knowledge of the many elements on this earth, life was pretty hard on earth with so little, now flash forward to the creation of a whole new generation. Antoine Lavoisier is known as the father of chemistry. In 1787 Antoine Lavoisier wrote a book called Elements of Chemistry. He put together the first complete list of elements, discovered and named oxygen and hydrogen, helped develop the metric system, and helped to reform chemical nomenclature. Prior to chemistry, there was alchemy. Alchemy was unsuccessful in explaining the nature of matter and its transformations however by doing these experiments and recording the results, alchemists set the stage for modern chemistry. The difference of these two was noticed by Robert Boyle. Alchemy and chemistry are both concerned with matter and its transformations but chemistry uses scientific methods to prove their work. Robert Boyle wrote about this in his book titled The Skeptical Chemist. The Periodic Table is an arrangement of elements. There are 118 elements listed in the periodic table. The elements in the table are presented in order of increasing atomic number. The Periodic Table was created by Dmitri Mendeleev. He presented his period... ... middle of paper ... ...y ready and the child had an allergic reaction. Over the next few days, Collip worked hard to improve the extract, and a second dose was injected on January 23. This injection was completely successful. The first American patient to get a dose of insulin was Elizabeth Hughes Gossett, who was the daughter of the governor of New York. Frederick Banting and J.J.R. Macleod were awarded the Nobel Prize in Physiology or Medicine in 1923 for the discovery of insulin. Frederick Sanger was able to discover the structure of Insulin. It was the first protein to have its sequence determined. He was awarded the 1958 Nobel Prize in Chemistry for his work. The discovery of insulin was major towards our world due to the fact lots of people are diagnosed with diabetes. It certainly helped changed the world but it wouldn’t have been able to do that without the discovery of chemistry.

In this essay, the author

  • Explains that antoine lavoisier, the father of chemistry, wrote a book called elements of chemistry in 1787. alchemy was unsuccessful in explaining the nature of matter and its transformations.
  • Explains the periodic table, which is an arrangement of elements, created by dmitri mendeleev.
  • Explains john dalton's atomic theory, which states that all elements are made up of tiny particles called atoms and can be combined with other elements to form chemical compounds.
  • Explains that niels bohr's bohrs model was the first to show the structure of an atom. the quantum mechanical model changed the game in the 1920s.
  • Explains that atoms were built up from a more fundamental unit that couldn’t be bigger than hydrogen. friedrich kekule believed that the chemical structure of benzene was an ring-shaped arrangement of six carbon
  • Explains how the discovery of insulin changed the lives of many. banting, best, and macleod were awarded the nobel prize in physiology or medicine in 1923.
